This engagement ring with black onyx draws the eye with a deep, opaque black that carries no shimmer or translucency - a pure, concentrated colour. The cabochon cut gives the stone a smooth, slightly domed surface, over which light glides quietly without scattering. The very big size of the stone gives the ring a bold, confident presence on the hand, while the modern, understated setting keeps attention on the onyx itself. Jewellers have long linked this stone with strength and endurance, which is why it often finds its way onto the finger at engagement as a symbol of certainty.

Such a clean, deeply black onyx, free of spots or discolouration, is easy to overlook among other stones, yet a second one just as uniform is hard to find afterwards. Silver and good stones get more expensive year after year, so such a carefully chosen onyx at this price is a rarity today. The setting is made of pure, refined European silver of sterling silver 925, coated with a layer of rhodium that protects the surface against tarnishing and scratches - so the ring needs less everyday cleaning and keeps its shine for longer. The piece is stamped with the French maker's mark, which guarantees the origin of the metal. The alloy contains no nickel, the metal responsible for allergic reactions, so the ring can be worn without worrying about irritation.

For a meeting in the city, it pairs well with a beige trench coat and a thin, cool grey turtleneck - the onyx catches the eye against these muted tones as the hand rises in a gesture of greeting or passing a cup. It also suits a black blazer and a simple white shirt, where the black of the stone blends with the outfit while the rhodium-plated silver adds contrast. The very big size of the onyx gives the hand's gesture striking presence without the need for any additional jewellery.
