Lilith Coffin Cut Natural Herkimer Diamond Ring Set in 14K White Gold

The Lilith coffin cut Herkimer ring set centers a bold coffin-cut natural Herkimer “diamond” — a raw, clear quartz with celestial salt-and-pepper character — set in an Art Deco–inspired design and matched to a coordinating band, all in cool solid white gold. A dramatic, gothic-glam two-piece set for someone who wants their ring to look like the night sky.

The Herkimer diamond

A Herkimer “diamond” isn't a true diamond — it's a naturally faceted, doubly-terminated quartz famous for its clarity and raw crystalline sparkle. This coffin-cut center has a galaxy-like character, and because it's formed by nature, every stone is unique in clarity and inclusions. It's softer than diamond, so it appreciates gentle care. Our guide to salt-and-pepper diamonds and our non-traditional engagement ring guide are great reads for raw, celestial styles.

A two-piece set

The accents

Choose your side stones from the drop-down menu: moissanite (D color, 9.25 Mohs) or natural conflict-free diamond (G/H, I1, 10 Mohs), ~0.3ctw — brilliant white accents that frame the raw center.

Why solid white gold

This set is solid white gold — the metal itself, not plating or vermeil over a base metal. The cool white suits the crisp, icy Art Deco look. The color is permanent: it won't wear off and won't turn your skin green. Choose your karat or platinum below; yellow or rose gold is available on request.

Choose your metal & karat

Select your metal from the drop-down — every ring in this set is solid precious metal throughout, never plated. Each option keeps the same crisp, icy white backdrop that suits the Art Deco look.

Sizing & care

Herkimer quartz is softer than diamond, so treat it gently: avoid hard knocks and clean with warm soapy water and a soft cloth rather than ultrasonic or steam cleaners. Both rings should be ordered in the same size; please reference our sizing guide before ordering. An optional written appraisal can be added from the drop-down menu (non-refundable once completed).
