Why Herkimer Diamond
Herkimer diamonds are not true diamonds but a variety of double-terminated quartz crystal found almost exclusively in Herkimer County, New York. They form naturally with two pointed ends and exceptional clarity, making them a striking diamond alternative. Long associated with clarity and mental focus. Chosen for their natural facets, their brilliant light play, and their grounding quality. No mystical claims. Just a remarkable crystal with a clear, focused meaning that fits real life.

How This Handmade Gemstone Ring Is Made
Each Herkimer diamond ring is made to order in my small Santa Fe studio. Copper grows directly around the raw crystal through an electrical electroforming process, forming organically around the double-terminated structure. The natural facets catch and reflect light with every movement. No two rings are identical.
Sizing
Select your US ring size at checkout (4–15 available). The ~8mm crystal has a slightly more substantial presence than smaller stone rings. Between sizes? Size up for comfort. Need help? Email hello@blackbirdsagestudio.com and I’ll guide you through it.
Care
Remove before swimming, showering, or applying lotions. Store dry. Polish with a soft cloth to maintain shine (Bright finish) or let the patina deepen naturally (Antique finish). Herkimer diamonds are durable (7–7.5 Mohs) but treat gently to avoid chipping the natural crystal points.
