Forest-green fire and a scatter of stars, worn on two hands. This galaxy green fire opal couples ring set centers a kite-cut green fire opal for her — an iridescent stone that flashes color with every turn of the hand, framed in black onyx on bright sterling silver — beside a tungsten band for him inlaid with green fire opal and crushed galaxy sandstone. An heirloom-worthy his-and-hers pairing for couples whose love feels a little out of this world.

Two rings, one love story
Some couples are grounded and green; others are dreamers who watch the night sky. This set is for the ones who are both. Her iridescent green ring and his cosmic galaxy band are designed to be worn together — one of the most romantic pairings in our collection of celestial couple rings — yet each stands beautifully on its own as an engagement ring, wedding band, promise ring, or anniversary gift. If you're still weighing options, our guide to the best matching rings for couples in 2026 is a lovely place to start.
Her Rings
Solid 925 sterling silver in a bright rhodium finish, centered on a kite-cut green fire opal with black onyx and starry-night accents. A slim, comfort-fit stacking design.
His Ring
An 8 mm comfort-fit tungsten carbide band inlaid with green fire opal and crushed galaxy sandstone — rugged, scratch-resistant, and quietly spectacular.
The green fire opal
Green fire opal is a vivid, living stone — forest-green depths lit by flashes of color that shift as the light moves. Opal is the October birthstone and a timeless symbol of hope and creativity, which makes this set a meaningful October birthday, engagement, or anniversary gift.

The galaxy men's band
His band pairs the same green fire opal with a channel of shimmering galaxy sandstone, so the surface glimmers like a slice of the night sky. Set into ultra-durable tungsten carbide, it's built for a lifetime of everyday wear. Discover more in our collection of opal couples rings.
Metals & everyday wear
Her rings are solid 925 sterling silver finished in rhodium for a crisp, white-gold look; his is tungsten carbide, one of the hardest, most scratch-resistant metals in fine jewelry, with a comfort-fit interior. Both are hypoallergenic and nickel-free, and her rings can be upgraded to solid gold on request.
