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)

the rings have arrived they are absolutely stuning ! i thank you with all my heart and i pay no duties thanks to you THANK YOU VERY MUCH I HAVE NO WORDS TO THANKS !! Mencaglia A of Bucharest Romania (bought two blue topaz diamond rings)

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)

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)

What is a Chameleon Diamond? – How Does a Chameleon Diamond Change Color?
Fancy colored diamonds that have the unusual characteristic of changing color when exposed to daylight are know in the diamond trade as "chameleon" diamonds. In normal conditions Chameleon diamonds have a unique olive-grey and greenish color and they change to either a brown color or to a yellowish color. These strange diamonds are among the most unusual of all gemstones due to their unique characteristic of undergoing a color change due to thermal variations. The most typical way to see this phenomenon is to place the diamond in a dark cool place for a couple of days. After the couple of days, look at the diamond in low light conditions, then take the diamond to a warmer place in similar light conditions and carefully watch the color change; this type of color change is known as photochroism. The color change might be very subtle but if observed carefully it should be noticeable. Chameleon diamonds are also sensitive to different lighting types and will show different colors if observed under halogen light, incandescent light and daylight. Additionally, if Chameleon diamonds are exposed to a lot of heat (250° C), they can change to a greenish-yellowish color very quickly and when they cool down and stabilize their normal color will return; this is known as thermochroism. With all Natural fancy color diamonds, an element other than carbon has made its way into the diamond which results in a new color. In the case of Chameleon diamonds, an excess of hydrogen and a small amount of nitrogen has entered the diamond and creates the unique color-changing property.

The Biggest and Most Famous Chameleon Diamonds – Amazing Natural Fancy Chameleon Diamonds
Since Chameleon diamonds possess unique photochroism and thermochroism properties they are extremely rare and desirable. The biggest Chameleon diamond ever found weighed 30.00 carats, and the bigger the chameleon diamond the more dramatic the color change. One of the most amazing Chameleon diamonds is a stunning 8.04 carat radiant cut diamond that was evaluated by GIA and classified as “Fancy Dark Grey Green Chameleon”. It is set in an extraordinary ring surrounded by pink pave diamonds and pink gold. Due to the rarity and beauty, that Chameleon diamond is valued at $2,100,000. Another notable chameleon diamond sold for $240,000 at an auction in Hong Kong; it is over 4 carats and set in a spectacular platinum ring.

Buying a Chameleon Diamond – Always Buy A Chameleon Diamond With a GIA Certificate
The best way to ensure that you are buying a quality diamond is to look for a GIA Certificate. GIA is a non-profit institution; they do not buy, sell or appraise diamonds, rather they focus on education and research. GIA has been trusted by fine jewelers worldwide for over 50 years to provide the highest standards of reliability and assurance. Based on the 4C’s of diamonds—clarity, cut, color and carat—GIA provides a reputable and comprehensive analysis of the quality and authenticity of each stone. All of our Fancy Chameleon Diamonds come with GIA certificates so that you can be sure you are purchasing a quality stone.
