Hi Marc, This is Amazing! I've never experienced such fast shipping! I was noticed on a Wednesday that my items had been shipped, and on already on the following Monday I had the parcel at home! From US to Sweden in Europe! The Tanzanites I ordered are perfectly just what I requested! Thank you very much Marc! This means a lot for me! I will for sure recommend you further and come back for more orders! Wish you a nice day! Best regards, Queenie H. of Stockholm Sweden (bought loose tanzanites)
Hi Marc, I received my ring today. It fits perfectly, the color of the topaz is beautiful! I almost wish I had chosen a larger stone. Thank you, Mary A. of Modesto CA (bought a swiss blue topaz gold ring)
Cardy was AMAZING! It took 45 minutes. Everyone warned me that I would be without my ring for weeks, and you helped me get away from that. You have been extremely responsive and fantastic for all of this. I really appreciate you, and DEFINITELY would recommend you to anyone I can. You are very much running your business very well. Not to mention, my ring is beautiful!!! Exactly what I wanted. Katie F. of San Francisco CA (bought alexandrite engagement ring)
Hi Marc, I got my ring yesterday.. love it! Looks great! I like the way the prongs are done and the ruby is beautiful! Thanks, Brigitte L. (bought Chatham Ruby and AfricaGems made the ring)
Dear Marc, I have a confession to make. I lost my original engagement ring, a Stuller setting for an asscher cut and a cushion Chatham Sapphire. I wanted a ring that looked close to that original one. You made it happen! Actually, your mil grain work and stone setting was better than the original which was off centered. Thank you. Regards, Christine Y (bought Chatham Blue Sapphire and we made the ring)
Marc, Received the stone. It’s beautiful! We now have a new place to order stones from and feel confident in the quality! Thank You, Clayton M. (bought loose pink tourmaline gem)
Hi Marc, Thank you, I received the stone on Wednesday as you indicated. I appreciate the quick turn around time. Pleasure doing business with you and your site will be one of my top gem shopping sites after this business experience. I did enjoy the extra haribo snack. Thank you once again, Danny C. (bought a round 1 carat loose blue sapphire for engagement ring)
First diamonds are in the mail. Had gone away for a week and nobody at home dropped the mail in the box. Apologies. Picked up my pendant with the new ones and they look beautiful. My next purchase will be emeralds...Thanks, Marc. Li B (bought and exchanged enhanced blue diamonds)
Hi Marc, The bracelet arrived this morning and as you said it looks stunning and I know she will love it. Could you please send a Cert of Authenticity (Similar to the one sent for the 2 loose stones) and a full invoice for the total amount for insurance purposes at my end. If you need to send copies by post please send to, Alan H. (bought a tanzanite bracelet)
Hi Marc, I just wanted to say how delighted I was to receive the Tanzanite bracelet for Christmas. I understand from my husband, Alan, that you were extremely helpful with the making of the bracelet, it sounds like it caused a few problems at times, not least due to Alans bank! I just wanted to let you know that I am thrilled with the bracelet, the stones are beautiful and it looks lovely, so thank you for all your help! I hope you and your family had a good Christmas and very best wishes for a healthy, happy New Year. Kind regards, Sue H. (husband bought tanzanite bracelet)
Hi Marc, I just received the opal and it is gorgeous, as always I am very pleased with my purchase. I was looking at different pendants, it's a Christmas present for my daughter. I saw a multi-gem one that I liked. Item pendant 650870s. Should I order it on line or could you just do it. Also will you extend the 25 off discount on that item? Again, thanks for all your help,Terese U. (bought stunning loose black opal gem)
Good Afternoon Marc, Thank you so much selling me this amazing stone, I can assure you it will be well loved. I thought you might enjoy how much people love the blue spinel you sold me. I posted a few photos on PS last night and will likely post more in the next few days. Again thank you, I really do love it and I am wearing it even as I type this! Katherine S. (bought large blue spinel gemstone)
My wifes stone got here this morning. She was in awe of how gorgeous a stone it was. It is replacing a stone in a ring that was stolen and in our opinion we think it is even nicer than the stone it replaced. Once set we will be whole again lol. Again thank you for having the stone available and for you call concerning shipping. We will certainly recommend you to any of our friends who are looking for QUALITY stones. Doc Mc (bought loose oval padparadscha gemstone)
Hi Marc- just wanted to thank you for finding the 4.4mm size for me, and also for the quick refund on the 4mm. So glad I found your website! Cristy S. (bought loose white sapphires)
Hi Marc, I just want to say thank you so much! The pendant is so beautiful..well done! The bale also fits perfectly. I have a question about the negative ions created by tourmaline..now can one just wear it to experience the negative ions or does there have to be pressure applied to release the negative ions? I'm just curious. Thank you Dawn T (bought custom tourmaline pendant)
Marc, The ring arrrived yesterday and it is gorgeous! Thank you so much for creating the perfect piece with this sapphire. This ring will become an heirloom. Henry G (bought custom spessartite garnet ring)
Marc, Thank you so much! You may have thought it took longer than expected but we thought it was quite expedient. Thank you for continually confirming for us our decision to purchase from Africa Gems. This has been a wonderful transaction. We'll be here all day so as soon as it arrives I'll let you know. Happy Valentine's Day, Jennefer P of San Deigo CA (bought custom emerald ring & band)
I'll put them in the mail today. I want you to know that I really appreciate how amenable you have been. Your A+ rating is exactly right. I will continue to do business with you when I have other needs. My sister has also been checking out the site for sapphires based on the excellent service I received. Thanks again, Jim W.of Bangor MI (bought loose emeralds)
Will do! I'm in Denver on business until Saturday. I'll get it shipped out ASAP upon my return - next Monday most likely. Thank you for all of your help. Especially your guarantee and return policy. Made purchasing the gem online much more comfortable. Ironically, my jeweler also loosely knew your father and had a very good opinion of him. Thanks again Marc! Doug M from Camarillo CA (bought loose blue sapphire)
Marc, Your fantastic customer service makes it easy to support AfricaGems! Looking forward to surprising my wife with the Onyx ring. Regards, Michael S. from Boise ID (bought onyx diamond pendant)
Hi Marc, So far I'm very happy with the sapphire I purchased. My plan is to mount it in a tanzanite ring that I have (the tanzanite is very light in color and I've never been happy with it which is a surprise since it's also a Levian purchase). The setting has two sides with the stone suspended in between. I think the light will catch it magnificently! Thanks for checking on my order! Rita K. from Garland TX (bought Chatham emerald stone)
Hi Marc, Just to let you know that the stone was delivered today. Pitty it is dark now so can not see the true stae, but I am happy to see it here with the certs!I hope to do business with you again in the future! Thank you for you help, patience, Regards Wim D. of Dubai (bought loose oval alexandrite)

Dear Marc, I just received the four turquoise gemstones that I had ordered. They are beautiful. I am very happy with the quality and will be ordering some more gemstones soon.Thanks Baljinder K. (bought loose turquoise gems)
Marc, I just wanted to let you know that I received the ring today and it’s beautiful, she’s gonna love it! Thank you again for all you’ve done. I was concerned about ordering something liker this over the internet but you’ve made this entire process very easy and your communication with me has been outstanding. Everything was exactly as you described it…perfect! David M. of Atlanta GA (bought custom Alexandrite diamond ring)
I received the Tsavorites Friday and I was stunned with the quality of the stones I received. I was worried about ordering calibrated stones without even having a picture of the exact stones I'd be receiving, but you didn't disappoint. The description said to expect some yellow, I didn't detect any yellow at all, if anything I picked up on a slight hint of blue which is very desirable. Anyhow, I had them set today, they hold their color and are bright in even the worst lighting. Thank you! Greg R. of St. Paul MN (bought Tsavorite gemstones)
Thank you for inquiring about the possible upgrade. The ring is too beautiful to jeopardize its integrity. I now will know the next time to use the chart when ordering. It is amazing how it changes color according to the light source. Thank you again, Lisa M. of Spokane WA (bought custom chatham alexandrite ring)
Again, beautiful quality. Am relieved they finally got here! Thanks for your help Cheers, Sonia R. of Tasmania (bought loose citrine gems)
Hi Marc, I received the alexandrite. The quality exceeded my expectations. Your stone was much nicer than anything that I saw locally. You got a repeat customer!

Thanks Marc….a loooong road but all ended as we wanted Thank you for following up Michael D. from Naples FL (bought loose spessartite garnet)
The aquamarine stones arrived yesterday. Lovely color, as are all stones I have received from Africa Gems! They are already set in gold earring mounts and in my ears. Love them! Thank you! Renny B. from Province MA (bought loose aquamarines)
Marc, The ring is magnificent! Well worth the wait. Betty is very happy. The full cut diamonds make a world of difference and show off the alexandrite very nicely. I can't thank you enough for your excellent sales and service. --- If your up to it, I have another job for you. Eugene M from Albany NY (bought custom alkexandrite ring)

Marc, The ring is great! We always wanted those alexandrites to stay together, and the bypass ring was the perfect solution. It's always a pleasure to work with you. Your attention to customer satisfaction and quality workmanship are first rate. Thanks, Eugene M. from Albany NY (bought custom alexandrite diamond ring)
Marc, I received my replacement alexandrites today and I absolutely love them. They are perfect. Thank you so much for your quick response, attention to detail and wonderful customer service. Doing business with Africa Gems has been a lovely experience and I look forward to doing business with you in the future. God bless. Lisa L. of Dover PA (bought loose alexandrite gems)

When someone says sapphire most people think of a clear rich blue color gemstone. That is appropriate because the word sapphire comes from the Latin word sapphirus which then became the Greek word sappheiros and meant blue or blue stone. Some believe that based on ancient writings the Latin word sappheiros originally referred to what we now call lapis lazuli not the glorious blue corundum we think of in todays gemstone world. Unfortunately, no one knows exactly when the word sapphire came to refer only to the clear blue corundum gemstone.We know today that corundum comes in many colors other than blue. Other gemstones like garnet and tourmaline come in several colors, but sapphire is second to none when it comes to the range of colors. The range of colors would make a rainbow green with envy. The colors range from white (colorless) to black with just about every imaginable color in between including color changing sapphire. Sapphire comes in every color but red because red corundum is called ruby. It may be interesting to note that it wasn't known until fairly recent modern chemical analysis (around 1800) that ruby was actually the same corundum gemstone as sapphire.History of Sapphires
Throughout history, sapphire has been known as a gem of royalty, elegance and wealth and dates back to the seventh century BC. Some believe that the Ten Commandments were written on tablets of sapphire. Ancient Persians even believed that the heavens or sky was a sapphire in which the Earth was embedded. It would almost make sense because sapphire comes in the shades of blue seen in the sky deep blue twilight or bright blue mid-day and so many shades in between. Marco Polo described sapphires in his thirteenth century book detaining his visit to the island of Serendib (Sri Lanka).Sapphire Lore & Sapphire Mystical Properties
Many cultures believed that sapphires had healing properties; that sapphires brought good fortune, virtue, holiness, wisdom, sincerity, and faithfulness; that sapphires made stupid men wise and ill tempered men good tempered; that sapphires promoted feelings of sympathy and harmony. The British Crown Jewels contain many large blue sapphires meant to symbolize pure and wise rulers.
Over the years, sapphires have become known as the birthstone for those born in September, as the Zodiac birthstone for those born under the sign of Taurus and as the anniversary gemstone for the 5th and 45th anniversaries.Colors of Faceted Sapphire
Blue is arguably the most popular color with both men and women, so it is no wonder that blue sapphire is a highly desirable gemstone. In the gemstone world the word sapphire refers the blue variety of gemstone. All other colors of sapphire are called fancy sapphires with the specific color descriptor used to define the sapphire. Star sapphires are also part of the fancy sapphire family.For the last decade or so rainbow sapphire jewelry has been very popular. The fancy colors hadn't been as readily available as they have been for the last decade or so. The fancy colors previously were available to those in the know but were not carried by most jewelers. As a matter of course they were usually a special order item. Fancy colors of sapphire can run the gamut from pastel to very vivid and intense color is something to tickle everyones fancy. The color of the sapphire is determined by the natural chemical trace elements that act as colorants.Blue Sapphire - Cornflower Blue Sapphire - Royal Blue Sapphire Gemstones
Blue sapphire can range from a clear soft baby blue to the most intense and vivid blue. The most valuable blue sapphires have the darker more vivid color which has been described as a rich royal or cornflower blue but those descriptors are somewhat subjective. Some sapphire connoisseurs prefer a sapphire that has a minimum of secondary purplish hue while others prefer the more velvety blue color that a more purplish secondary hue offers. Either way it is the secondary hue that defines whether the sapphire is a royal blue or a cornflower blue. Sapphires with a secondary purple hue that is between 10 to 15 percent purple will most often be defined as royal blue while sapphires with between 5 to 10 percent purple will most often be defined as cornflower blue. Sapphires that are almost black that are often sold as midnight blue are probably the least valuable grade of blue sapphires. See below for an example of blue sapphire color grading.Sapphire Origin
Gemologists can most often tell the origin of a sapphire based on its color and its inclusions. Blue sapphire from Burma (now officially known as the Republic of the Union of Myanmar) typically have fewer inclusions and are perceived as having a more crisp color than Kashmir (India) sapphires, which are described as having a more velvety sleepy appearance. The Kashmir mines have been effectively mine out since the 1930s so Kashmir sapphires are truly rare.Orange Sapphire Gemstones
Orange sapphire can be found in color from a pale brownish color to a vivid bright and lively orange. If the color leans toward a blend of pink and orange, the sapphire may be the very, very rare and very highly prized Padparadscha sapphire. Padparadscha is a color of sapphire that has been given its own name rather than being classified as either pink or orange. It is believed that the name was meant to represent the color of an oriental lotus blossom, but as with the color description of cornflower blue what does that really mean? Lotus blossoms are typically a beautiful delicate reddish pink as buds but as they open the pink turns to shades of yellow.Rare Padparadscha Sapphires
The name Padparadscha is given to those sapphires that are light to medium tones of pinkish-orange with hues ranging from orangey-pink to orange-pink. It is a color which is difficult to define by the actual percentages of pink and orange hues. Padparadscha sapphires may have secondary hues of yellow or violet making it much more difficult to define. Probably the best word to describe the best color of a Padparadscha is delicate. Most gemologists believe that for a sapphire to be called Padparadscha it must contain both pink and orange. The need for a gemologist to define whether or not a specific sapphire can be called Padparadscha is critical given the rarity and cost of these sapphires. All too often, orange sapphires are offered for sale as Padparadscha as are pink sapphire that have been treated with beryllium to create the Padparadscha color. Always get a gemological report when purchasing a Padparadscha sapphire.Loose Pink Sapphire Gemstones
Pink sapphire can range from a soft pastel yet lively baby pink to a intense hot pink to very intense vibrant magenta pink. The line separating a pink sapphire from a ruby isn't always clear and can sometime be difficult to define even among gemologists. It is the depth of color that most easily separates ruby from pink sapphire. Some believe that the closer to the red of a ruby, the more valuable the pink sapphire. See below for an example of pink sapphire grading. New deposits of pink sapphire were found in Madagascar in the late 1990's making pink sapphire much more available. Many of these sapphires seem to glow from within even in low light. If you are a lover of pink then pink sapphire could be the gemstone to collect as it comes in a wide range of pink tones.Violet / Purple / Lavender Sapphire Gemstones
The color range of purple or violet sapphire might surprise many. Violet sapphire in the 19th century was mistakenly called Oriental amethyst but with the advances in gemology and better gemstone identification, that name is no longer used. Violet or purple sapphire is a color of sapphire that many would appreciate if they knew it existed. It is not a color of sapphire that you easily find in most jewelry stores. Violet / purple sapphire can range from a violet blue to a violet red to a violet pink with a myriad of tones in-between. The color of a violet or purple sapphire can put a top quality amethyst to shame. Violet / purple sapphires are very rarely found in carat weights over 10 carats, but are available in smaller carat weights. Of particular note, there are now sapphires available that the gemstone trade is calling berry sapphire. They are natural in color and not subject to any kind of thermal or heat treatment that most sapphires undergo. Their colors range from purplish red to pinkish purple, fuchsia pink, violet to blue lavender. Just picture blueberries and boysenberries and you get the idea.Interesting Color Change Sapphire Gems
Color change sapphire is almost never seen in jewelry stores. They are truly a rare phenomenon. Top quality color change sapphires can completely change color depending on the light source. They can change from an amethyst purple to a shade of blue violet in direct sunlight. Some believe that the best color change sapphire change from a bluish green in daylight to a red or reddish purple in incandescent light, much like the color change of an alexandrite.White (colorless) Sapphire
White sapphire has been used as a diamond substitute in jewelry for years. While it is a little more expensive than white (colorless topaz) it sparkles more like diamond making it a better substitute. Slices of white sapphire are often used as watch crystals because of the resistance to scratching and the overall durability of sapphire.
Green sapphire is a relatively uncommon color of sapphire and most usually found in only small to medium sizes of carat weight. In the 19th century it was often mistakenly called oriental emerald. Green sapphire can be a strong, bright green or a bluish or yellowish green or an olive green or it can be very pale.Yellow Sapphire Gemstones
Yellow sapphire can range from soft pale pastel yellow to intense vibrant sunshine or canary yellow. Yellow sapphire can be a gold, honey or brownish yellow. Bright canary yellow sapphires have been used as substitutes for canary yellow diamonds and are a less expensive alternative. One has to be a real connoisseur or a gemologist to know the difference and when someone is looking at a set yellow sapphire from across the room (yes they can be bright enough to be seen across a room) no one but you would know the difference. Top quality yellow sapphires look beautiful in just about every light from direct sunlight to incandescent indoor lighting. Lighter yellow sapphires are not necessarily less desirable or valuable than canary yellow sapphire. When it comes to yellow sapphire, the intensity of the color is more of a personal choice than one set by a standard. Some believe that a medium vibrant canary yellow is the best as it typically is the most in-demand yellow sapphire.What is The Best Quality Sapphire Gem?
Bottom line, what color of sapphire is best for you may be a subjective thing. The best blue sapphire may be too dark for you when seen in artificial light and you might prefer a lighter blue that will still sparkle in artificial or low lights. Or you may prefer pink or yellow in general as they are inherently brighter colors. Or you may prefer pastel colors in general so the lighter hues and tones of any of the colors of sapphire may be the best choice for you. Someone else may prefer the bright vivid darker colors and that works too because sapphire comes in such a wide range of hues and tones and colors.Star Sapphires
Star sapphires are sapphires wherein the rutile inclusions (needle like inclusions) create a phenomenon known as asterism. If Mother Nature has done her job right, these inclusions create a six legged star that appears in the gemstone. If she has done her job right, they star will have perfect symmetry and center of the star will appear to move when the light source is moved. The star should be clear and crisp when viewed under a single light source such as the sun or a flashlight but it will be less defined in diffused light. And sometimes the rutiles are so perfectly arranged that the sapphire will appear to have two or more stars in the sapphire when there are two or more powerful light sources closely aligned as each light source will produce its own star. It's a marvel of reflection. Star sapphires are typically cut as cabochon gemstones. Star sapphires can be just any color including a grayish white or black. Unfortunately the more transparent the gemstone the less pronounced the star.Sapphire Gemstone Evaluation
Color, color, color!
As with all gemstones, one needs to consider color, clarity, cut and carat weight. When thinking about sapphire, color is the most important factor with clarity second and cut and carat weight after that. The difficulty may be picking a color you like more than another. Hue
Sapphires have primary and secondary hues so pure blue or pink or yellow with no secondary hue is just about impossible to find. Using the GIA rating system, a ratio of 80% / 20% is probably the average for good sapphires on the market today. Tone
The color tone in a sapphire should be between 75 and 80 percent to be ideal. No matter what the color of the sapphire it should not be too dark or too light in tone. If they are below 60% they will appear washed out and those with tone above 80% will be very dark.
Example of Blue Sapphire Grades:
Examples of Pink Sapphire Grades:
Saturation ranges from "grayish / brown" to "vivid". Think of the word "intensity" when evaluating saturation. There are 6 levels of saturation. Bottom line, a buyer should look for a bright luminescent color sapphire. Clarity
Sapphire is a Type II gemstone and by nature has natural inclusions. Sapphires have rutile inclusions - threadlike inclusions often called "Silk". Those inclusions are noted in a range from VVS (Very Very Slightly included) to Included 3 - Prominent (Inclusions which have a pronounced affect on the beauty of the stone and possibility the durability). Unlike the clarity scale for diamonds which starts at IF (Internally Flawless), the GIA clarity chart for colored gemstones starts at VVS. Other types of gemstone reports can show a sapphire with more descriptive report - for example, an GEM Grade and a description of eye clean, medium dark color, brilliance, excellent cut and polish would be a real prize and very expensive - a true collector-connoisseurs gemstone. Cut
The cut of a sapphire is almost as important as the clarity. Well cut sapphires will show off the color and clarity and the sapphire will be positively brilliant. Sapphires are cut in just about every shape with some gemologists believing that oval, pear and cushion cut are the best for sapphires because those shapes work best with the outline of the rough. But round shapes can be more brilliant but are not commonly found in larger carat weight sapphires. Carat Weight
Carat weight is arguably the least import of the 4Cs when it comes to sapphires. Just be aware that a smaller sapphire of top color and clarity can be much more valuable than a larger sapphire of lesser color / clarity. In fact a top quality sapphire can be more valuable per carat than a diamond of similar size because there are far fewer top quality sapphires than there are top quality diamonds, especially when one is looking at carat weights over 3 carats.Buying A Loose Sapphire?
A buyer who is considering the purchase of a loose sapphire gemstone of any color should request a professional gemological report in order to help them know exactly what they are purchasing. Grading reports may be shown using a numerical value and / or percent or be given an overall letter (B thru AAA to GEM) and description "grade" for the clarity and color - it will depend on with which laboratory the gemologist trained. There are several recognized laboratories like Gemological Institute of America (GIA - uses the numerical scale), International Gemological Institute (IGI), International Gem Society (IGS), European Gemological Center (EGC) and more.Sapphire Treatments
Without question a completely natural, untreated and unheated sapphire of top color and clarity will be more valuable than a heat treated sapphire. Some will quote a price as much as 3 times the cost of a heat treated sapphire of the same size. For example, a Padparadscha sapphire that has not been heat treated could easily be even more than 3 times the cost of a heat treated Padparadscha give the rarity of Padparadscha to begin with. That said it is estimated that 90+% of all sapphires are heat treated. Heat treatment is considered a natural treatment, i.e. a continuation of what Mother Nature started. Heat treatment helps improve the color and clarity of a natural sapphire and is considered a permanent treatment requiring no special care.Diffusion Treatments
There is a newer heat treatment used by those that may less than scrupulous. It is called lattice deep diffusion. It takes heat treatment to a whole new level. Basically, the process adds chemicals to the heat processes and it can take a near colorless sapphire and actually add color. It was improved so that it could be used on sapphire that started with some color but that was heavily zoned and the color could then be evenly distributed through the gemstone. Those selling diffusion treated gemstones should not be stating heat treated or natural when advertising or selling these treated gemstones. They should be disclosing the gemstone has been chemically colored by diffusion.Sapphire Treatment Disclosure
In the US, gemstone treatments must be disclosed. Some large retail chain stores may have a generic statement to the effect that precious and semi-precious stones may have been treated or enhanced but the sales personnel do not have the specifics about any treatments for a specific gemstone or gemstones especially for "accent" gemstones. If purchasing a large gemstone, 1) ask for an individual gemstone report from a gemologist or baring availability of that, ask the sales person to write on the sales receipt any treatment types that they are aware of for that specific gemstone, what the return policy is for the store is and take your gem to an independent gemologist - appraiser. If you didn't get what you paid for then take it back to the store. It is best to buy loose gemstones from a gemstone dealer you trust when purchasing an expensive gemstone.Synthetic Sapphire
Synthetic corundum, either sapphire or ruby has been around since the beginning of the 1900's. That 3 plus carat exquisite blue sapphire that Grandma left to you may not be a natural sapphire unless Grandma just happened to be very wealthy. Much of the synthetic corundum is being manufactured these days mostly for industrial use in lasers, medical equipment, as a polishing aid and for watch crystals. Laboratory created sapphire does have a place in jewelry but it should be sold as laboratory created and priced accordingly. There are glass imitations on the market pretending to be sapphire but these are usually found in costume jewelry.Sapphire is one of the most durable gemstones next to diamond. Sapphire is rated a 9 on the Mohs sale of hardness making it suitable for jewelry that can be worn every day. That isn't to say that one should wear sapphire jewelry while gardening or doing other activities where a gemstone is exposed to hard knocks or exposed to chemicals or solvents. Like all gemstone jewelry, jewelry set with sapphire it is meant to worn and enjoyed but not put to the test to see how much abuse the gemstone or the setting can take.
