A black onyx cabochon sits at the centre of this ring, its smooth, domed surface reflecting light in one calm pool, without scattering or flicker. Two small cubic zirconia stones are set on either side, giving a cool sparkle that contrasts with the matte depth of the onyx. The solitaire form stays simple and minimalist - the band doesn't draw attention away from the stone, and its small size keeps the ring sitting close to the finger. The same design works equally well as a solitaire for everyday wear and as an engagement ring for couples who favour a modern, understated form. In old-world jewellery craft, black onyx was associated with strength, endurance and confidence - an association that still holds today.

For this piece we select onyx stones with an even, deep black colour and a clean surface, free of streaks or discolouration, which is especially visible given the small size of the stone. Good-quality stones like these rise in price along with silver, so buying at today's price makes sense. The band is made of refined European sterling silver 925, coated with a layer of rhodium - a hard metal that protects the surface against scratching and dulling, so the shine lasts a long time. The alloy contains no nickel or other allergenic additives, so the ring can be worn without concerns about skin irritation. The metal is signed with the French maker's mark - a guarantee of the silver's quality and origin.

Black onyx pairs well with natural fabrics - a linen shirt, a cotton dress or a loose sweater in muted tones. When the hand rests on a table or holds a cup, the stone draws the eye with its depth. In summer it suits light linen and beige, in winter dark wool and charcoal sweaters. This is a ring equally at home in everyday activities and as the symbol of an important decision.
