Fire caught in the dark. This black fire opal engagement ring centers a 6×8mm oval black fire opal — a deep, near-black body flashing red, orange, and crimson as it catches the light — framed by natural black onyx accents that scatter across the band like embers. Sculpted leaf detail wraps the shoulders in nature-inspired romance, all in 14K rose gold vermeil over sterling silver 925. Warm rose gold, moody black-and-crimson stone: an alternative engagement ring for anyone who finds a plain white solitaire a little too quiet.

The black fire opal center
Black fire opal is one of the most dramatic looks in jewelry: a dark, near-black base body shot through with intense play-of-color that flashes red, orange, and crimson as the stone moves under your hand. This lab-created opal shares the same fundamental structure as natural opal — hydrated silica arranged to diffract light — and produces the same mesmerizing fire, with more consistent color and a gentler price. No two opals ever show exactly the same pattern of fire, so the way yours flickers is uniquely its own. It is a natural fit for the moody world of our black onyx engagement rings and gothic engagement rings.
The natural black onyx accents
Set along the band are natural black onyx accents — a natural chalcedony with a deep, glossy jet-black surface that picks up the dark base of the opal and grounds its crimson fire with quiet points of shadow. The onyx is genuine and naturally dark, never dyed. Together the two stones tell a single black-and-fire story, the kind of tight, deliberate color pairing you will find across our black onyx couples rings.
The leaf shoulders and silhouette
From the center setting, the shoulders curve into sculpted leaf detail that softens the drama of the stones and ties the ring to nature-inspired, fairytale-leaning aesthetics. The leafwork also does quiet practical work: it catches light from several angles and gives the band visual weight on the finger without heaviness. It is gothic-romantic in spirit but organic in execution — flame and foliage in the same ring.
Meaning and symbolism
Opal has long been tied to love, passion, and emotional intensity — the play-of-color was once imagined as fire trapped inside the stone, and opal is the October birthstone and the traditional 14th-anniversary gem. Black onyx brings its own centuries-old language of strength and protection. For couples who want symbolism with a little heat behind it, the pairing is hard to beat. Read more in our journal on black onyx meaning, our October birthstone guide, and our guide to gothic wedding rings.

Sizing & care
Choose your size at checkout; if you are unsure or between sizes, message us before ordering and we will help, with resizing available from a modest fee. Opal is softer than most engagement-ring stones, so treat it gently: remove the ring for impact-heavy activities, avoid harsh chemicals and ultrasonic cleaners, keep it away from sudden temperature changes, and clean with a soft cloth and warm water only. With sensible care, an opal ring can be worn and loved for a very long time.
Frequently asked questions
Is the black fire opal real?
Yes — it is a real lab-created opal. Lab-created opal is genuine opal material, with the same silica structure and the same play-of-color as natural opal, grown under controlled conditions rather than mined. The fire opal look refers to the intense red and crimson flashing through the deep black base.
Is the black onyx natural?
Yes. The black accents along the band are natural black onyx, a natural chalcedony with a deep, glossy jet-black finish. It is genuine and naturally dark, never dyed.
Will my opal look exactly like the photos?
It will share the same deep black base and fiery red-crimson play-of-color, but the exact pattern of fire is unique to every opal. That one-of-a-kind flicker is the whole point of the stone, not a flaw.
What is rose gold vermeil?
Rose gold vermeil is real 14K rose gold over sterling silver 925 — the warm, golden look of rose gold at an easier price. If you would like gold all the way through, the same design is also available in solid gold.
How big is the center stone?
The oval black fire opal measures about 6 × 8 mm, roughly 1.4 carats. Ovals spread wider than they are deep, so the stone reads generously on the finger.
Is this a good October birthstone gift?
Yes. Opal is the traditional October birthstone and the 14th-anniversary gem, so the ring works beautifully as a proposal, birthday, or anniversary piece for an October-born partner.
How durable is opal for daily wear?
Opal is softer than harder stones, at about 5.5 to 6.5 on the Mohs scale, so it asks for gentler treatment: avoid impact, harsh chemicals, ultrasonic cleaners, and sudden temperature changes. With sensible care it wears wonderfully as a daily ring.
What does black fire opal symbolize?
Opal has long been linked to love, passion, and emotional intensity, its play-of-color once imagined as captured fire. Black fire opal carries that meaning in a deeper, more dramatic key, paired here with the strength traditionally associated with black onyx.
Can this be worn as an engagement or promise ring?
Absolutely. The substantial center stone and considered design give it the presence of an engagement ring, and it also makes a striking promise ring or right-hand statement piece.
Can this ring be resized?
Yes, within reason. We recommend ordering your correct size where possible; if you need guidance, contact us before ordering and resizing starts from a modest fee.
Are the stones ethically sourced?
Yes. The lab-created opal has no mining footprint, and the natural black onyx accents are ethically sourced and conflict-free.
How should I clean it?
Wipe gently with a soft cloth and warm water only, avoiding harsh cleaners and ultrasonic machines. Remove the ring before showering, swimming, exercise, or applying lotions and fragrance, and store it dry in the velvet box.
Does it arrive gift-ready?
Yes. Every order ships in a free luxury velvet gift box, backed by our lifetime warranty — ready for a proposal or to give as a keepsake.
