A ring with black onyx brings a quiet, deep contrast into a classic look. The cabochon cut leaves the stone's surface unbroken by facets, drawing out a dense, even black and a soft, matte play of light across its curve, with no sharp reflections to distract the eye. Onyx has long found its way into engagement rings and solitaire settings as a symbol of endurance, strength and self-assurance, a fitting choice for a hand meant to wear something more than mere decoration.

Each stone for this ring is chosen by hand, checked under light for depth of black and freedom from discoloration. Onyx of this clarity is growing harder to source, since nature cannot be pressed to yield more of it, and that scarcity pushes the price up. Silver and other precious metals are also rising in price, so buying at a reasonable price today makes sense. Refined European silver holds the stone in an alloy of high purity: the 925 fineness confirms the absence of nickel and other harmful additives, which is why the ring does not irritate the skin. A rhodium layer protects the surface against tarnishing and scratches, so the silver needs cleaning less often. The maker's mark struck on the piece is registered with the French assay office and attests to the origin of the metal.

A ring like this sits well on the hand at a meeting in the city, under the sleeve of a trench coat, or against a roll-neck in a cool, neutral shade of grey or beige. Black onyx does not compete with the rest of the outfit, but introduces a single firm point of focus, visible with every movement of the hand. Its medium size and weight of 2.6 grams keep the ring light on the finger, while the solitaire form stays legible up close and from a distance.
