Two rings, one love story
Some couples are grounded and calm; others are dreamers chasing the horizon. This set is for the ones who are both. Her glowing opal ring and his geometric hexagon sapphire band are designed to be worn together — one of the most striking 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're 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 bright rhodium finish, cradling a blue fire opal that flashes with teal, violet and green, framed by brilliant accent stones.
His Ring
An 8 mm comfort-fit tungsten carbide band set with a striking hexagon-cut sapphire — modern, geometric, scratch-resistant and quietly bold.
The blue fire opal
Blue fire opal is mesmerizing — a luminous stone that shifts with flashes of teal, violet and green as it catches the light. As the October birthstone, opal has long symbolized hope, creativity and passion. Here the center is a blue fire opal, chosen for its vivid play-of-color, surrounded by sparkling cubic-zirconia accents. Opal lovers can explore more in our fire opal ring guide.
The hexagon sapphire men's band
His band centers on a bold hexagon-cut sapphire, its geometric silhouette a modern counterpoint to her softer curves. Sapphire is a timeless emblem of loyalty and enduring love — you can read the full story in our sapphire meaning guide. Here it is a simulated sapphire, hand-set for rich saturated blue and set into ultra-durable tungsten carbide for a lifetime of everyday wear. See more pairings in our gemstone couples rings.
Metals & everyday wear
Her ring is 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 ring can be upgraded to solid gold on request. Discover the whole range in our couples rings collection.
