Double A (AA) grade Herkimer Diamonds are natural water-clear, double-terminated quartz crystals as the photos/photographs show. With 18 natural facets, a high quality "AA" grade Herkimer crystal is flawless to the naked eye. It can be dropped in a glass of water and virtually disappear. This grade of gem is rare in any size over of an inch. With a hardness of 7-7.5 out of a possible 10, it's an excellent choice for earrings or other jewelry. They are actually more rare than a real diamond!
Also check the Atypical page for larger Herkimer Diamonds with excellent clarity.

All the Herkimer Diamonds photographed and listed for sale were mined in Herkimer, NY, one of the few places on Earth these unique quartz crystals have been found. Mother Nature out did herself creating these brilliant gem stones. Enjoy the photographs.

Please Note: We are beginning to see some sellers grading Herkimer Diamonds with a AAA Grade. HerkimerCrystalsOnline.com considers "AA Grade" the highest quality Herkimer Diamonds.
Some of our AA grade diamonds could be classified as an AAA grade. Like wise, some of our AA Grade Herkimer's are borderline A Grade crystals.
