Bold, dark and quietly regal. This black onyx ring set centers a princess-cut natural black onyx — jet-black, high-gloss and mirror-smooth — framed by a halo of bright simulated diamonds and wrapped in warm 14K yellow gold vermeil. Designed as a two-piece set, the engagement ring and its matching band read like a piece of vintage jewelry reimagined for someone who wants their romance a shade more daring.

A vintage silhouette in gold and black
There is something timeless about the pairing of golden metal and midnight-black stone. The princess-cut onyx sits square and confident at the center, its sharp corners catching light against the soft glow of the gold, while a frame of small stones adds a vintage, heirloom-drawer feel. It is a look made for anyone drawn to black onyx engagement rings and the drama of a non-traditional proposal — elegant enough for the everyday, striking enough to be remembered.
The engagement ring
Holds the princess-cut black onyx in a haloed setting — the statement piece and focal point of the pairing.
The matching band
A slender accented band shaped to nest cleanly against the engagement ring, completing the set. Lovely stacked or worn alone from our black onyx couples rings.
The natural black onyx
Black onyx is a natural chalcedony — a stone prized for centuries for its deep, even, glossy black and its cool, substantial feel on the hand. Ours is cut and polished to a true jet finish so the surface reflects light like still water. To understand why this stone has held such a place in jewelry and folklore, our guide to black onyx meaning is a rich place to start, and our overview of black gemstones shows how onyx compares to other dark stones.
A halo of simulated diamonds
Surrounding the onyx is a scattering of simulated diamonds, chosen for their crisp, brilliant white sparkle. They frame the dark center with a ring of light, so the black stone reads even deeper and the whole design catches the eye from across a room. It is a bright, budget-friendly way to add classic engagement-ring shimmer, and it plays beautifully against the warmth of the gold.
Warm 14K yellow gold vermeil
The set is finished in 14K yellow gold vermeil — a generous layer of real gold over a core of sterling silver 925. That golden tone is what gives the ring its vintage warmth and makes the black onyx feel jewel-like rather than stark. It is the detail that lets an accessible set carry the presence of something far more precious.
What black onyx symbolizes
Long regarded as a stone of strength, protection and steady resolve, black onyx has been worn as a talisman for grounding and quiet confidence. That makes it a meaningful choice for a couple — a symbol of a bond that holds firm. If black is becoming your signature, you will find more of it across our black onyx wedding bands, and our feature on the October birthstone traces the deeper history of dark gemstones in jewelry.

Frequently asked questions
Is the black onyx natural?
Yes. The center is a natural black onyx, a genuine chalcedony cut and polished to a deep, glossy jet-black finish. Its rich, even color is a hallmark of the stone.
Does this come as a set?
Yes — it includes the black onyx engagement ring plus a matching accented band designed to nest alongside it. The band can also be worn on its own as a promise or stacking ring.
What is yellow gold vermeil?
Yellow gold vermeil is real gold layered over sterling silver 925 — the warm, golden look of gold at a much easier price. If you would prefer gold all the way through, the same design is also available in solid gold.
What are the accent stones?
The center onyx is framed by simulated diamonds, chosen for their crisp, brilliant white sparkle. They add classic engagement-ring shimmer and make the black stone read even deeper.
What cut is the center stone?
A princess cut — a square shape with crisp corners, measuring roughly 5.0 x 5.0 mm for about 1.4 ct. It gives the onyx a clean, contemporary edge.
Can I wear this as an engagement ring?
Absolutely. It is designed as a non-traditional engagement or bridal set, and it also makes a striking promise ring, anniversary gift or statement piece.
Is black onyx suitable for daily wear?
Black onyx sits around 6.5 to 7 on the Mohs scale, making it well suited to everyday wear with normal care. Avoid hard knocks and remove the rings for rough activities to keep the polish pristine.
Can it be engraved?
Yes. You can add a personal engraving of up to 16 characters at checkout — a date, initials or a short message. Engraved pieces are final sale, so please double-check spelling.
How do I care for it?
Remove the rings before showering, swimming or exercise, avoid contact with lotions and fragrance, and store them dry in the velvet box between wears. A soft dry cloth restores the shine.
