Fire and midnight, worn on two hands. This red fire opal couples ring set in black tungsten pairs an 8 mm men's band with a 4 mm women's band, both aglow with crushed red fire opal layered over starry blue goldstone and framed in hammered black tungsten — a bold, unmistakably matched pair for couples who like a little drama in their love story.

His & hers
Two rings, one fire
Some couples are drawn to the dramatic — deep blacks, glowing reds, a design that turns heads. This set was made for them: two hammered black tungsten bands that share the same molten inlay, so the same flash of fire travels across both hands. It is one of the boldest pairings among our opal couples rings, yet each band stands on its own. If you are weighing options, our guide to the best matching rings for couples in 2026 is a lovely place to start.
For Him, 8 mm
Hammered black tungsten carbide with a comfort-fit interior — a wider statement band whose full inlay channel gives the fire opal and goldstone real presence.
For Her, 4 mm
The same hammered black tungsten and identical inlay in a slimmer profile — stackable, yet striking entirely on its own.
The fire opal inlay
Each ring carries a hand-set, two-layer inlay. The base is shimmering blue goldstone flecked with copper that catches light like a starfield; layered over it, crushed red fire opal flashes orange, pink, and red as the light shifts. Fire opal is the October birthstone, loved for its warm play-of-color — and opal admirers can explore more glowing designs in our fire opal ring guide. Because each inlay is hand-arranged before the resin sets, the two rings are siblings rather than identical twins.
Metals & everyday wear
Both bands are hammered and brushed black tungsten carbide, with the black bonded into the alloy itself for a deep, lasting finish. Tungsten is one of the hardest metals in fine jewelry; both bands are hypoallergenic and nickel-free, and a solid silver or solid gold upgrade is available on request.

Frequently asked questions
Is this sold as a matching set?
Yes — it is a two-piece his & hers couples set with an 8 mm men's band and a 4 mm women's band that share the same inlay, hammered finish, and comfort-fit profile. Each ring is also available separately.
What is the red inlay?
Genuine crushed red fire opal, prized for its play-of-color that flashes orange, pink, and red. It is sealed into a resin channel so the color stays vivid and the surface stays smooth.
What is the sparkling blue base layer?
Blue goldstone — a rich, coppery blue material flecked with tiny crystals that sparkle like stars. It forms the shimmering base beneath the crushed fire opal.
Does this set have a birthstone?
Yes — opal is the October birthstone, which makes this set a meaningful choice for an October birthday.
What are the band widths?
His band is 8 mm and her band is 4 mm.
Will the black finish stay rich?
Yes — the black is bonded into the tungsten carbide alloy itself rather than plated on top, so it keeps its deep tone through everyday wear.
Are the bands hypoallergenic?
Yes. Tungsten carbide is nickel-free and gentle on sensitive skin, so neither band will discolour fingers.
Are the rings designed to look like a matched pair?
Yes — they share the same hammered black tungsten exterior, the same fire opal and goldstone inlay, and the same comfort-fit profile. Only the width differs: 8 mm for him, 4 mm for her.
Can we buy the bands individually?
Yes — each ring is also available separately if you only need one band.
