Fantasy-inspired, handcrafted jewelry
Herkimer "diamonds" aren't diamonds at all — they're a remarkably clear, naturally double-terminated quartz found only in Herkimer County, New York, prized for a brilliance that rivals cut glass. In a kite cut, that natural clarity fills a sharp four-sided silhouette with light, making a kite cut Herkimer diamond engagement ring an unusual, earth-rooted alternative for couples who want something genuinely uncommon. Each is handcrafted in 925 sterling silver and solid 14K gold, with the stone always disclosed honestly as Herkimer quartz, never as diamond.

A Stone With a Sense of Place
A kite cut Herkimer diamond engagement ring carries a story most stones can't. Herkimer "diamonds" are a naturally double-terminated quartz found in only one place on earth — Herkimer County, New York — and prized for an exceptional natural clarity and brilliance that needs little help to shine. Cut into a kite, that clarity fills the elongated, four-sided silhouette with clean light, making a ring that's both strikingly modern and rooted in a specific patch of earth. Each is set by hand in 925 sterling silver and solid 14K gold.
Honest by Name
Despite the name, Herkimer "diamonds" are quartz, not diamonds — and Aquamarise® always discloses them honestly as exactly that. What they offer is a genuinely natural, clear stone with a unique geological story, at a price far below diamond, for couples who value origin and individuality over a traditional gem.
Caring for a Kite Cut Herkimer Ring
As a quartz, Herkimer sits at Mohs 7, durable enough for the kite cut with a protective setting around the points and reasonable everyday care. Clean gently with warm soapy water and a soft cloth, and keep it from hard knocks. See our jewelry care guide.
