His & hers
Two rings, one love story
Some couples are dreamers who watch the stars; others carry the whole cosmos in how they love. This set is for both. Her tanzanite ring and his Orion Nebula 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, a wedding band, or an anniversary gift. If you are still weighing options, our guide to the best matching rings for couples in 2026 is a lovely place to start.
Her Ring
Solid 925 sterling silver in a dramatic blackened black-ruthenium finish that makes the violet-blue stone glow, set with a marquise simulated tanzanite (5 x 10 mm, approx. 0.7 ct) framed by brilliant accents. Slim 1.6 mm band.
His Ring
An 8 mm comfort-fit black tungsten carbide band with our Orion Nebula inlay of galaxy sandstone and glowing purple fire opal, finished with a silhouetted tree line — rugged, scratch-resistant, and quietly spectacular.
The tanzanite
Tanzanite glows in that unmistakable violet-blue found in only one place on earth, and as the December birthstone it makes this set a heartfelt gift for a winter birthday, engagement, or anniversary. Here the marquise center is a simulated tanzanite, hand-set for that deep, saturated color and brilliant sparkle, with cubic-zirconia accents catching the light around it. Explore more pairings in our full range of gemstone couples rings.
The Orion Nebula men’s band
His band is our signature Orion Nebula design: a channel of shimmering galaxy sandstone streaked with crushed purple fire opal, so the surface glows like a nebula caught in metal, framed by a tree-line silhouette. Set into ultra-durable black tungsten carbide, it is built for a lifetime of everyday wear.
Metals & everyday wear
Her ring is solid 925 sterling silver in a blackened black-ruthenium finish for a striking, moody backdrop; his is black 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 ring can be upgraded to solid gold on request.
