Herkimer "Diamond" Quartz Tumbled Stone Jewelry Chain Pendant - Gemstone A Quality #7128

Gemstone Tumbled Stone Pendant Made of Herkimer "Diamond" Quartz with Tourmaline – with Fabric Cord

An exceptional tumbled stone pendant made of Herkimer "Diamond" Quartz with fine tourmaline inclusions – a fascinating interplay of clear crystal energy and dark, natural structure. The transparency of the quartz and the striking tourmaline veins give the stone a special depth and make each piece a unique natural specimen.

The gemstone measures approx. 29 × 25 mm and has a bore of approx. 2.5 mm. This allows the pendant to be worn in many ways – suitable for common leather cords, omega necklaces, or delicate silver chains.
The included black fabric cord (approx. 80 cm) is soft, supple, and guarantees comfortable wear.

Please note: The Herkimer "Diamond" is not a real diamond, but a particularly clear, double-terminated rock crystal (quartz). The name refers to its extraordinary sparkle and its original discovery site in Herkimer County (USA).

You will receive exactly the gemstone tumbled stone pendant pictured – a unique piece of nature.
