Two rings, one dark romance
Her nature-inspired leaf ring and his crushed-opal band are designed to be worn together — both glowing against deep, moody colour — yet each stands beautifully alone as an engagement ring, a wedding band or an anniversary gift. It is one of the most atmospheric pairings among our dark romance couple rings. 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
Rose-gold vermeil over solid 925 sterling silver, hand-detailed with a botanical leaf gallery.
Oval black fire opal center, framed by black onyx accents.
His Ring
A rose-gold tungsten carbide band with a crushed black fire opal inlay.
Comfort-fit interior, built for everyday wear.
Black fire opal & the October birthstone
The oval black fire opal glows from a dark base with sudden flashes of fire, the kind of stone that changes with the light. Opal is the October birthstone and a long-held emblem of hope, imagination and captured light, making this set a meaningful choice for an October couple or anyone drawn to celestial, low-lit colour. You can read more in our fire opal engagement rings guide.
The leaf design & black onyx
Her band curls into a delicate botanical leaf gallery, one of the signatures of our leaf couples rings, while framing black onyx — a grounding, protective stone long tied to strength and steady resolve. You can read more about it in our guide to black onyx meaning.
Metals & everyday wear
Her ring is rose-gold vermeil — a thick layer of rose gold over solid 925 sterling silver — while his is rose-gold tungsten carbide, one of the hardest metals in fine jewellery, with a comfort-fit interior. Both are hypoallergenic and nickel-free, and her ring can be upgraded to solid gold on request.
