This engagement ring with black onyx catches the eye with a deep, uniform black rarely found in a single stone. It was precisely this purity of colour, with no trace of blotching, that decided the choice of this particular stone. The faceted cut divides the surface into small facets that catch the light as the hand turns, answering with brief flashes. The vintage form, with a delicately slender band, gives the ring a character straight out of old engagement jewelry. Onyx has long been credited with strength and endurance, and jewellers also valued it as a symbol of self-confidence.

Good stones of this class are becoming harder to find, and silver prices are rising, so buying today makes financial sense. The setting is made of refined European silver, sterling silver 925, coated with a layer of rhodium that protects the surface from tarnishing, dulling and light scratches. This means the ring needs less everyday care, and its shine lasts longer. The alloy contains no nickel, the metal responsible for allergic reactions, so wearing it does not irritate the skin. The piece is stamped with the French maker's mark, which guarantees the origin of the metal. The weight of 2.2 g is felt on the hand as a light but distinct heft, typical of a solidly made silver band.

For office wear, this ring pairs well with a plain shirt and a blazer in muted, cool colours - grey and charcoal best set off the black of the onyx. The gesture of handing over documents or holding a cup becomes a moment for the stone to draw attention. In the evening, it works well with a simple, dark dress, where the faceted cut of the onyx answers the light of candles or lamps. The small size of the ring means it suits narrow, delicate fingers without weighing down the hand.
