Dear Mr. Sarosi, The ring just arrived. I do not mind telling you that the photograph did not do it justice, it is wonderful. I have been searching for this ring since I saw one in a painting over forty years ago. Thank you. Michael A of Boise ID (bought black onyx 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)

Black Onyx Gemstones - Beautiful Black Onyx Its Magical
Black onyx is part of the beautiful chalcedony family of gemstones which includes agate, cornelian, and chrysoprase. Black onyx as a gemstone became popular in ancient Greek and Roman times. It was and is used not only in jewelry but for decorative items around the house. Some black onyx forms in parallel layers of black and white which makes it very suitable for cameo or intaglio carving either for jewelry or plaques or cups or many other items.

Black Onyx Stones Look Great in Jewelry
The black onyx carried by is uni-colored black chalcedony. It has a hardness of 7 on the Mohs scale and it is perfect as a background for setting with gemstones of color especially those that are bright in color like yellow or pink sapphire, emeralds or tsavorite, rubies or diamonds. It is also beautiful set in yellow or white gold or silver all by itself. For many years, it was very popular and became a classic for gents rings and it is beautiful set with marcasite or used in Victorian style jewelry.
