UV Reactive Herkimer Diamond Ring

This listing is for 1 ring. There are multiple rings available. One ring will ne chosen at random upon purchase. If you woukd like a specific ring, please leave an order note! Herkimer diamonds are double-terminated quartz crystals discovered within exposed outcrops of dolomite in and around Herkimer County, New York, and the Mohawk River Valley in the US. They are not diamonds; the "diamond" in their name is due to both their clarity and well formed faces. Because the first discovery sites were in the village of Middleville and in the city of Little Falls, respectively, the crystal is also known as a Middleville diamond or a Little Falls diamond. These stones are also UV reactive as they contain inclusions of petroleum.  Each ring is sterling silver and adjustable.
