A mountain range at dusk and the aurora above it, worn on two hands. This Borealis tanzanite & teal sapphire couples ring set pairs a marquise tanzanite cradled in silver for her with a Northern Lights mountain-range band for him — a his-and-hers pairing for couples who chase horizons and the winter sky together.

Two rings, one love story
Some couples find each other on trailheads and mountain passes; others fall for the light that dances over them after dark. This set is for the ones who are both. Her marquise-cut ring and his aurora-lit mountain band are made to be worn together — one of the most atmospheric pairings among our celestial couples rings — yet each stands beautifully alone as an engagement ring, wedding band, or anniversary gift. If you are still deciding, our edit of the best matching rings for couples in 2026 is a lovely place to begin.
Her Ring
Solid 925 sterling silver, hand-detailed to hold a marquise-cut tanzanite in violet-blue, framed by brilliant teal sapphire accents that echo alpine ice and glacial water.
His Ring
A comfort-fit tungsten carbide band engraved with a Northern Lights mountain range — rugged, scratch-resistant, and quietly cinematic on the hand.
The tanzanite & teal sapphire
Tanzanite glows in that rare violet-blue found nowhere else, and as a December birthstone it carries all the quiet magic of winter light. Here the marquise center is a simulated tanzanite, hand-set for its saturated colour and brilliant sparkle, surrounded by teal sapphire accents. Couples drawn to coloured stones will find kindred pieces throughout our gemstone couples rings.
The Northern Lights men's band
His band turns a tungsten surface into a landscape: a mountain-range silhouette beneath a sky washed in aurora tones, so the whole ring reads like a night spent under the Borealis. Set into ultra-durable tungsten carbide, it is built for a lifetime of everyday wear and sits comfortably alongside the rest of our couples rings. For guidance on choosing a matching pair, our notes on wedding ring sets for him and her walk through everything worth knowing.
Metals & everyday wear
Her ring is solid 925 sterling silver for a bright, timeless finish; 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.
