Lilith Coffin Cut Black Onyx Ring Set in 14K White Gold

An onyx engagement ring set of pure gothic romance: a natural black onyx coffin cut stone — 6 × 10 mm, approx. 2.4 carats — framed in hand-beaded milgrain above a split shank of graduated accents, paired with a curved chevron band that cradles the coffin's point like a crown of stars. Choose moissanite or natural diamond accents, in white gold or platinum.

Till Death — and After

The coffin cut is the boldest silhouette in gothic bridal jewelry: an elongated hexagonal step cut whose tapered shoulders mirror a Victorian casket — a memento mori turned love token, a promise that not even death does part. Here, the jet-black onyx is framed by a delicate milgrain halo, its thousands of hand-beaded grains catching light around the darkness. The split shank carries graduated accent stones down each shoulder, and the companion contour band curves beneath the coffin's point with its own arc of graduated stones, finishing in a milgrain pear drop.

The Natural Black Onyx: 6 × 10 mm, Approx. 2.4 Carats

The center is genuine natural onyx — the classic stone of gothic jewelry, prized since antiquity as a talisman of protection, strength, and grounded resolve. Cut as a 6 × 10 mm coffin of approximately 2.4 carats, its surface is a deep, glass-smooth black that swallows light where the accent stones scatter it. Because onyx is opaque and evenly saturated, it holds its perfect black in any light — day or candlelight.

Choose Your Accent Stones

Moissanite — genuine lab-grown gemstones with more rainbow fire than diamond (refractive index 2.65 vs 2.42), at a more accessible price.

Natural Diamonds — earth-mined white diamonds for those who want traditional diamonds beside the natural onyx.

Either way, the graduated accents run down both shoulders of the engagement ring and across the chevron band — icy white points of light against the black center.

Your Metal: White Gold or Platinum

Select 10K, 14K, or 18K white gold, or platinum, from the drop-down. Every option is genuine solid precious metal — nothing plated over brass, nothing to wear away. White gold is rhodium-finished for a bright mirror luster; platinum is naturally white all the way through and the densest, most durable choice. The cool silver-white tones are the classic pairing for black stones, sharpening the onyx's darkness by contrast.

This set belongs to our Lovers of the Dark™ black engagement rings and solid gold engagement rings collections — and pairs beautifully with the rest of our black rings.

Care & Craftsmanship

Each set is made to order over 2–6 weeks — cast, beaded, and set for your order specifically. Clean with warm water, mild soap, and a soft brush; onyx prefers gentle care, so skip harsh chemicals and ultrasonic cleaners. Store the rings in their velvet box when not worn, and remove them before heavy lifting or abrasive work.
