Description
A double-terminated Herkimer diamond — ~8mm, natural facets, exceptional clarity — encased in textured copper. Light catches in the crystal’s points with every movement, creating brilliant flashes that are hard to ignore. Clear, focused, entirely yours.
Herkimer diamonds are associated with clarity, focus, and amplification — a stone for intention-setting and sharp mental presence.
Materials & Specifications
Stone: Raw Herkimer diamond quartz — ~8mm, double-terminated with natural facets and exceptional clarity. Each crystal is unique.
Metal: Electroformed copper — Bright (warm, polished shine) or Antique (aged patina, earthy depth)
Band Width: ~2–3mm with organic copper texture
Size: Custom sized for you, US 4–15
Origin: Handcrafted in Santa Fe, New Mexico
How It’s Made
Each ring is made to order in my small Santa Fe studio. Copper is slowly deposited around the raw Herkimer diamond over several hours using traditional electroforming techniques, forming organically around the crystal’s 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 — if between sizes, size up for comfort. Need help? Email hello@blackbirdsagestudio.com — 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.
