A black onyx cabochon sits at the centre of the ring, its smooth, domed surface receding into shadow until closer light reveals a cool, metallic sheen right at the top of the stone. A deep, even black without streaks or discoloration gives this ring its modern, decisive character, easy to spot on the hand in motion. Onyx has long accompanied craftsmen working in stone as a symbol of perseverance and self-assurance, and in this setting it takes the form of an engagement and promise ring.

Only a small share of the sorted raw material makes it into this cut - what counts is an even black free of cracks and flaws, so selection is strict and the result shows immediately on the surface of the stone. Silver and other precious metals keep rising in price, so buying a well-chosen stone at a reasonable price makes sense right now. Beneath the stone sits pure, refined European sterling silver 925, coated with a layer of rhodium, a hard metal resistant to scratching, which protects the surface against tarnishing and dulling, so the shine lasts. The alloy contains no nickel or other harmful additives, so the band does not irritate the skin even with daily wear. The piece bears the French maker's mark, which guarantees the origin of the metal.

For everyday wear, the ring pairs well with a linen shirt in a natural shade or a loose cotton sweater - the black of the onyx stands out clearly against light, raw fabric and draws the eye without any extra ornamentation. The simple, modern form of the band does not distract from the stone, and the medium size of the cabochon means the ring sits well on the hand with every gesture. It is a piece just as easy to wear at the office as for an evening out in a simpler, understated outfit.
