Herkimer Diamond Ring / new Set in 925 sterling silver New and unworn 10.4 mm x 7.7 mm Weight: 2.86 g / 14.3 ct Ring size: EU 54 UK N US 6.8 FR 14 Inner diameter 17.2 mm Herkimer diamonds are twinned quartz crystals found in exposed dolomite outcrops in and around Herkimer County, New York, and in the Mohawk River Valley in the USA. It is not diamonds; the name "diamond" owes its origin to their clarity and the well-formed faces. Since the first finds were in the village of Middleville or in the town of Little Falls, the crystal is also referred to as Middleville Diamond or Little Falls Diamond. Herkimer diamonds gained fame after workers discovered them in large quantities in the late 18th century during dolomite mining in the Mohawk River Valley. Geologists discovered exposed dolomite in the outcrops of Herkimer County and began mining there, which led to the designation "Herkimer Diamond". Twinned quartz crystals are found worldwide.
