A matching set for modern couples
Made for couples who love clean, contemporary design, this two-piece set pairs a slim 4 mm band with a bolder 8 mm band. The brushed, faceted sterling silver adds quiet texture, while the smooth bezel settings keep a sleek, snag-free profile for everyday wear. It is one of the most understated pairings among our sterling silver couples rings, and each band stands beautifully on its own. If you are choosing together, our guide to the best matching rings for couples in 2026 is a lovely place to start.
The 8 mm Band
A bolder 8 mm width in brushed 925 sterling silver with a triangle bezel-set natural Herkimer stone — substantial and modern.
The 4 mm Band
A slim 4 mm width in the same brushed silver and matching triangle bezel setting — a refined everyday companion piece.
The Herkimer stones
Each band features a triangle-cut natural Herkimer quartz — a famously clear, double-terminated crystal that takes a bright, glassy polish. Every stone is naturally unique, with tiny inclusions that give a subtle salt-and-pepper character, so no two sets look exactly alike. That one-of-a-kind quality makes this set feel deeply personal among our wider collection of couples rings, and if you are comparing his-and-hers styles, our guide on choosing wedding ring sets for him and her is worth a read.
Metals & everyday wear
Both bands are solid 925 sterling silver with a brushed rhodium finish for a bright, modern look and a comfortable interior fit. Both are hypoallergenic and nickel-free, and a solid gold upgrade is available on request.

What metal are the bands made from?
