Where deep shadow meets living color. This black onyx ring set in solid 925 sterling silver frames a kite-cut green fire opal — all shifting cerulean-green flashes — between the deep, glossy jet-black of natural onyx accents. Two coordinating rings, a bright rhodium finish, and a mood that is equal parts dark romance and coastal dream.

A kite-cut set with dark-romantic drama
The sleek kite silhouette gives this set a modern, geometric edge, while the jet-black onyx accents wrap the fiery opal in shadow. Worn together, the two rings frame the center stone from both sides so the color seems to float in a bed of black. It is a design made for anyone who loves the moody, non-traditional look of our kite cut black onyx engagement rings and the wider black onyx engagement rings collection.
The engagement ring
Holds the kite-cut green fire opal accented with jet-black onyx — the statement piece and focal point of the set.
The matching band
A slender coordinating band that nests alongside the main ring, completing the silhouette. Lovely stacked or worn solo, and a natural match for our black onyx couples rings.
The natural black onyx
Black onyx is a natural chalcedony, a form of quartz cherished for its solid, even color and glassy polish. Here it appears as pure, saturated jet-black with a soft luminous sheen — the ideal dark frame to make the opal's colors leap forward. Sitting around 6.5 to 7 on the Mohs hardness scale, it is comfortably suited to a set you wear every day. For the lore behind the stone, our guide to black onyx meaning is a wonderful starting point.
A kite-cut green fire opal center
At the heart of the set sits a simulated green fire opal, cut into a crisp kite and alive with shifting flashes of cerulean and sea-green. Its glowing play-of-color is what gives the set its magic, and against the flat black of the onyx those hues look brighter and more electric than ever. It is a vivid, budget-friendly way to bring color and light to a dark, dramatic design.
Solid sterling silver with a rhodium finish
Both rings are crafted in solid 925 sterling silver and finished with rhodium, the same precious metal used on fine white-gold jewelry. That rhodium layer gives each band a bright, mirror-white luster and adds protection that helps resist tarnish and everyday scratches, keeping the silver looking freshly polished. It is the detail that lets a sterling silver set wear like something far more expensive.
What black onyx symbolizes
Black onyx has long been a stone of strength, protection and grounded resolve — a fitting emblem for two people building something steady together. Paired with the opal's flash of color and possibility, the set becomes a quiet promise: passion held safe by inner strength.

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 rings before showering, swimming or applying lotions, and store them in the velvet box when not worn. A soft, dry cloth restores the onyx polish and rhodium shine. Please note the book box shown is for styling only; your set arrives in a luxurious velvet ring box.
Frequently asked questions
Is the black onyx natural?
Yes. The accent stones are natural black onyx, a natural chalcedony prized for its even, glossy jet-black color, hand-set in solid 925 sterling silver.
Does this come as a set?
Yes. It includes the kite-cut fire opal engagement ring plus a matching band designed to nest alongside it. The band can also be worn on its own as a promise or stacking ring.
Is the fire opal a natural stone?
The center is a simulated green fire opal, chosen for its vivid, consistent play-of-color and bright cerulean-green flashes. It gives the set its glowing color at a friendly price.
What makes this a black onyx ring set?
The jet-black natural onyx accents frame the design and set its dark, glossy tone across both rings, while the fire opal provides a luminous center of color.
What metal is the set made from?
Solid 925 sterling silver, finished with rhodium for a bright white luster and added protection against tarnish and scratches.
What does the rhodium finish do?
Rhodium is the same precious metal used to finish fine white gold. It gives the silver a mirror-bright shine and adds a protective layer that keeps both rings looking freshly polished.
Is black onyx durable enough 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 this be an engagement set?
Absolutely. It is designed as a bold, non-traditional engagement or promise set, and its dark-romantic character makes it a striking alternative to a classic solitaire pairing.
Will sterling silver turn my finger green?
No. Because it is genuine 925 sterling silver with a rhodium finish, it will not tarnish easily or leave marks on your skin. Green marks come from low-quality metals, not real sterling silver.
Can the rings be engraved?
Yes. You can add a personal engraving of up to 16 characters at checkout, such as a date, initials or a short message. Engraved pieces are final sale, so please double-check spelling.
How should I care for the set?
Remove both rings before showering, swimming or applying lotions, avoid harsh chemicals and ultrasonic cleaners, store them in the velvet box, and buff gently with a soft dry cloth to restore shine.
Are the stones ethically sourced?
Yes. All of our stones are ethically sourced and conflict-free, so you can wear the set 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.
