The deep, matte black of two black onyx stones gives this ring a bold, modern character. The cabochon cut isn't after sparkle - it brings out a smooth, even stone surface across which light moves quietly, without scattering. The form, with two stones set in a single mount, recalls the layout typical of multi-stone rings and promise rings, though here it's led by a distinctly contemporary, geometric line. In old-world craft, black onyx was linked to strength and endurance, its black tied to the wearer's self-assurance.

A piece like this - with such even, deep colour and a clean surface free of streaks - is easy to overlook, and finding another this well matched is far from a given. Silver and good stones get more expensive year after year, so buying at this price now makes sense. The ring is stamped with the French maker's mark, which attests the origin of the metal. The setting is pure, refined European silver, sterling silver 925, coated with a layer of rhodium - a hard metal that protects the surface from tarnishing and keeps its shine for a long time. The same alloy, free of nickel and other sensitising additives, keeps even sensitive skin on the hand comfortable.

In a total-black look - a black turtleneck or a simple silk blouse - it's this ring that catches the eye as the hand lifts in a gesture or smooths back the hair. The big size of the stones pairs well with plain, unadorned nails and minimalist jewellery on the other hand. It also works beautifully with a knit sweater in charcoal grey, where the black of the onyx stands out clearly against the background. Four and a half grams of silver sits securely on the finger without ever feeling heavy.
