This black onyx signet ring draws the eye with a deep, matte black in which the cabochon cut gently reflects light rather than scattering it. The classic, wide signet form sits well on the hand and lends a confident line to the gesture of the hand. Onyx has long accompanied rings of strong character - craftsmen have linked it with strength, endurance and self-assurance, which makes it a natural choice for a signet ring.

For this piece we chose onyx with a uniform, deep black free of streaks or translucence - it was precisely this purity of colour that decided its selection. Silver and good stones are rising in price, so buying a signet ring like this at today's price makes sense. Refined European silver 925 has been coated with a layer of rhodium, a hard metal that protects the surface against tarnishing and scratches, meaning the ring rarely needs cleaning or polishing. An alloy free of nickel and other sensitising additives makes the signet ring comfortable to wear even on sensitive skin. The piece bears the French maker's mark, which guarantees the origin of the metal.

A signet ring like this feels at home in city casual wear - under loose jeans and a white shirt it looks natural, while with a leather jacket it takes on a distinctly masculine, decisive character. It also works well as a permanent element of an everyday look, regardless of the season. The cabochon-cut onyx remains legible even in simpler outfits, since its black never gets lost against light or dark backgrounds. This onyx signet ring works well as a constant point in everyday styling.
