Hexagon Cut Rutilated Quartz & Black Onyx Ring in Sterling Silver

Deep, glossy and endlessly dark, natural black onyx sets the mood for this black onyx ring in solid 925 sterling silver. Twin jet-black onyx stones flank a hexagon-cut rutilated quartz threaded with golden needles, while a bright rhodium finish makes the whole design gleam. It is a moody, modern take on the engagement ring — part gemstone jewel, part gothic talisman.

A dark-romantic silhouette

The design leans into contrast: two cabochons of jet-black onyx sit either side of a luminous golden quartz, so light and shadow trade places as your hand moves. The geometry is clean and architectural, with the hexagon center giving it an edge that feels contemporary rather than fussy. If you are drawn to shadowy, non-traditional stones, you will find kindred pieces throughout our black onyx engagement rings and our darker, statement-making gothic engagement rings collections.

The natural black onyx

Black onyx is a natural chalcedony — a form of quartz — prized for centuries for its even, ink-dark body and mirror-like polish. It reads as pure, saturated black with a soft glassy sheen, the kind of color that makes silver and sparkle look brighter beside it. Sitting around 6.5 to 7 on the Mohs hardness scale, it is comfortably suited to a ring you wear often. To learn where its mystique comes from, our guide to black onyx meaning is a rich place to begin, and our overview of black gemstones shows how onyx compares with other dark stones.

A golden rutilated quartz center

At the heart of the ring, a hexagon-cut natural rutilated quartz catches the light in a completely different key. Fine golden rutile needles are suspended inside the clear crystal like captured sunbeams, so no two stones are ever quite alike. Set against the flat black of the onyx, the warm gold threads seem to glow — a play of light and dark that gives the ring its signature character.

Crisp simulated diamond accents

Petite simulated diamonds add flashes of white fire along the setting, sharpening the whole design with a clean, contemporary sparkle. They are a bright, budget-friendly way to frame the darker stones and lift the shine of the rhodium finish. Prefer a lab-grown diamond or moissanite upgrade instead?

Solid sterling silver with a rhodium finish

The ring is crafted in solid 925 sterling silver and finished with rhodium, the same precious metal used on fine white-gold jewelry. That rhodium layer gives the band a bright, mirror-white luster and adds protection that helps resist tarnish and everyday scratches, so the silver keeps its freshly polished look. It is the detail that lets a sterling silver ring wear like something far more expensive.

What black onyx symbolizes

Long regarded as a stone of strength, protection and grounded resolve, black onyx has always carried a quiet, self-possessed power — which is exactly why it suits a piece worn as a promise. It speaks of steadiness and inner focus, a fitting emblem for a bond built to last. For more on how dark stones have been worn and what they signify, see our feature on black rings for women.

Sizing & care

Choose your size at checkout. If you are between sizes or unsure, we are happy to help — and if the fit is not quite right, resizing is available and starts from a modest fee. Because black onyx is a natural stone, avoid harsh chemicals and ultrasonic cleaners; remove the ring before showering, swimming or applying lotions, and store it in the velvet box when not worn. A soft, dry cloth restores both the onyx shine and the rhodium luster. Pieces like this also sit beautifully alongside our black onyx wedding bands if you would like to build a stack.
