The crushed diamond band His band carries a channel of crushed simulated diamond — brilliant cubic zirconia set into gold tungsten so the surface glitters like frost catching sun. It is a bold, modern counterpoint to her opal, and part of what makes this one of our favourite opal couples rings. Metals & everyday wear Her ring is gold vermeil — a thick layer of gold over solid 925 sterling silver — while his is 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. Explore more in our gold couples rings.
