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.

Black Onyx Coffin Ring Set FAQs
Is the onyx real?
Yes — the center is genuine natural onyx, an opaque black chalcedony that has been carved into jewelry since antiquity. Its deep, even black is natural to the stone.
What is a coffin cut?
A coffin cut is an elongated hexagonal step cut with tapered shoulders that echo the silhouette of a Victorian casket. In bridal jewelry it carries a romantic gothic meaning: a love that outlasts even "till death do us part."
How big is the center stone?
The coffin cut onyx measures 6 × 10 mm — approximately 2.4 carats — a dramatic, elongated presence on the hand.
What does black onyx symbolize?
Onyx has been worn for millennia as a stone of protection, inner strength, and steadiness — a guardian stone. As an engagement stone it represents a bond with deep roots and quiet power.
Should I choose moissanite or natural diamond accents?
Moissanite offers more rainbow fire than diamond at a more accessible price; natural diamonds are the traditional choice, mined from the earth. Both give icy white sparkle against the black onyx — the choice is purely personal.
Are both rings included?
Yes — this is a complete two-ring bridal set: the coffin cut engagement ring and the contour chevron band, designed to nest together.
Do the two rings fit flush together?
Yes — the chevron band curves to trace the coffin's lower point, so the two nest as a single composition.
Which metal should I choose?
14K white gold is the classic balance of purity and everyday durability (our most popular). 10K is the most durable and most affordable; 18K carries the highest gold content; platinum is naturally white throughout and the most substantial. All are solid precious metal and will never turn skin green.
Is onyx durable enough for daily wear?
Onyx is around 6.5–7 on the Mohs scale — well suited to fine jewelry worn with normal care. Remove your rings for heavy or abrasive work and clean gently, and the stone will stay glass-smooth for decades.
Is this a gothic engagement ring?
Proudly — the coffin cut, black stone, and Victorian milgrain place it firmly in the gothic tradition, executed as refined fine jewelry rather than costume. It's part of our Lovers of the Dark™ collection.
How long does made to order take?
Each set is cast and set to order over 2–6 weeks. You'll receive tracking as soon as your rings ship.
Is this set conflict-free?
The onyx and moissanite are ethically sourced and conflict-free; natural diamond accents are sourced through suppliers compliant with the Kimberley Process.
