For women who choose darkness beautifully. This Victorian gothic black onyx ring sets a deep 12 x 6 mm marquise-cut natural onyx inside a six-prong crown, mounted on a 925 sterling silver band finished in smoky black ruthenium. Ornate scrollwork flows across both shoulders like iron garden fencing, giving the ring a dark Victorian character that stands apart from anything traditional — dramatic, precise, and entirely its own.

A marquise solitaire for dark romantics
Some stones catch the light and scatter it. Black onyx holds it, drinks it in, and gives nothing back — and that absolute depth is exactly what makes it right for a woman never drawn to the obvious. The marquise cut amplifies it: long, pointed at both ends and commanding in proportion, it elongates the finger and turns a simple solitaire into something with real presence. Paired with the intricate Victorian scrollwork curling along the band, the result is unmistakably gothic. It belongs beside our gothic engagement rings and leads our black onyx engagement rings. For the history behind the style, our journal on Victorian gothic engagement rings is a beautiful read.
The natural black onyx
The center is a natural black onyx, a natural chalcedony known for its deep, opaque, mirror-glossy black and steady, grounded presence. There is a reason onyx has never felt fragile or merely decorative — it feels deliberate and old in the best possible sense. As an engagement-ring stone, it makes a statement that has nothing to do with tradition and everything to do with intention. To understand its lore, our guide to black onyx meaning is a lovely place to start.
The black ruthenium finish
The band begins as 925 sterling silver, then is treated with black ruthenium, a rare metal from the platinum family. Ruthenium reads as a deep gunmetal — a blackened, smoky gray rather than a flat, painted jet-black — and that is precisely what lends the scrollwork its antique, gothic-vintage warmth. It does not chip, flake or turn the skin; it deepens the tone of the silver without masking its structure, so each curl of the Victorian detail reads clearly, shadow on shadow against the darkened band. The stone and the metal are not in contrast — they are in agreement. To learn how the finish is made, see our note on what black ruthenium is.
Who this ring is for
This is for the woman who has always known exactly what she wants — and what she wants has never been a round diamond in a plain gold band. For the gothic bride who wants a ring that feels like an heirloom from another century; for the dark romantic who has been waiting for jewelry that keeps up; for anyone who sees beauty in shadow, in Victorian ironwork, in a stone that absorbs rather than reflects. If that is you, this ring already belongs to you. Explore more in our black onyx wedding bands and gothic wedding ring styles.

Sizing & care
Choose your size at checkout. If you are between sizes or unsure, reach out — we are glad to help, and resizing is available and starts from a modest fee. To keep the black ruthenium finish deep and the onyx glossy, remove the ring before showering, swimming, cleaning or applying lotions and fragrance, and store it dry in its velvet box between wears. A soft, dry cloth restores the shine. Treated gently, the darkened silver keeps its smoky, Victorian character for the long life ahead.
Frequently asked questions
Is the black onyx natural?
Yes. The 12 x 6 mm marquise center is natural black onyx, a natural chalcedony prized for its deep, glossy, opaque black. Its light-drinking depth is the whole drama of the ring.
Is the ring pure black?
The onyx itself is a deep opaque black, while the band is finished in black ruthenium — a deep gunmetal, a blackened smoky gray rather than a flat painted jet-black. That is by design: the finish has genuine depth and an antique, gothic-vintage warmth, and it lets the Victorian scrollwork read clearly rather than vanishing into a dead-flat void.
What is black ruthenium?
Ruthenium is a rare precious metal from the platinum family. Applied over solid 925 sterling silver, it darkens the metal to a rich blackened tone. Because it is a precious-metal finish rather than a cheap coating, it is stable, hypoallergenic and does not turn the skin.
What metal is the ring made from?
Solid 925 sterling silver, finished in black ruthenium for its smoky, gothic depth. It is hallmarked sterling and hypoallergenic, not plated base metal.
How big is the center stone?
The marquise onyx measures 12 x 6 mm — a substantial, elongating silhouette held securely in a six-prong crown setting for real presence on the hand.
Why a marquise cut?
The long, pointed marquise elongates the finger and gives the ring commanding proportion — a shape that has dressed the hands of royalty and mourning romantics alike since the eighteenth century.
Is onyx durable enough for daily wear?
Black onyx sits around 6.5 to 7 on the Mohs scale, well suited to everyday wear with normal care. Avoid hard knocks and remove the ring for rough activities to keep the stone pristine.
Can I wear this as an engagement ring?
Absolutely. It is designed as a gothic engagement ring and alternative to the traditional solitaire — equally at home as a statement, promise or anniversary ring.
Will the finish wear off?
Black ruthenium is a durable platinum-group finish that resists flaking and chipping far better than ordinary plating. With gentle care it holds its deep tone; if you ever wish to refresh it after years of daily wear, re-finishing is available.
Does it pair with other bands?
Beautifully. It stacks naturally with plain or milgrain black bands — explore our black onyx wedding bands to build a complete look.
Can it be engraved?
Yes. Add a personal engraving of up to 16 characters at checkout — a date, initials or a few words. Engraved pieces are final sale, so please double-check the spelling.
Are the stones ethically sourced?
Yes. Our stones are ethically sourced and conflict-free, so you can wear the ring with complete peace of mind.
Does it arrive gift-ready?
Every order ships in a free luxury velvet gift box and is backed by our lifetime warranty — ready for a proposal or to give as a keepsake.
