Galaxy Alexandrite & Fire Opal Tungsten Couples Ring Set

Two hands, one galaxy. This galaxy alexandrite and fire opal couples ring set pairs a bold 8 mm men's band with a slim 4 mm women's band, both carrying the same swirling deep-space inlay of alexandrite, galaxy sandstone, and fire opal beneath mirror-polished tungsten — a matched pair for couples whose love feels a little written in the stars. Purple nebula inlay Lab-created alexandrite Fire opal & galaxy sandstone Tungsten carbide 8 mm + 4 mm widths His & hers Two rings, one cosmic story Some couples belong under an open night sky, tracing constellations together. This set was made for them: two tungsten bands that share a single deep-space color story, so the same nebula travels across both hands. It sits among the most romantic pairings in our collection of celestial couple rings, yet each band stands beautifully on its own. If you are still choosing, our guide to the best matching rings for couples in 2026 is a lovely place to begin. His Band, 8 mm A substantial dome-profile band in mirror-polished tungsten carbide, comfort-fit inside, carrying the full swirling purple nebula inlay. Her Band, 4 mm A slim, refined dome profile in the same mirror-polished tungsten with the identical cosmic inlay — elegant on its own or stacked. The nebula inlay Inspired by the Crab Nebula still glowing in violet and pink centuries after its supernova, the inlay layers crushed lab-created alexandrite with shimmering galaxy sandstone and glowing fire opal, so the surface reads like deep space caught in metal. Alexandrite is a June-born gemstone and fire opal an October birthstone, and opal lovers can discover more glowing designs in our fire opal ring guide or across our opal couples rings. Because crushed materials never settle twice the same way, each band is subtly one of a kind while the pair stays beautifully matched. Metals & everyday wear Both bands are tungsten carbide with a mirror-polish finish — one of the hardest metals in fine jewelry, prized for holding its shine through years of daily wear. Both are hypoallergenic and nickel-free, and a solid silver or solid gold upgrade is available on request.
