Black and deeply matte at rest, the onyx in this ring only comes alive under light - the facets catch the reflection and send it back across the stone's dark surface in short, sharp flashes. The solitaire form is simple and focused on a single stone, with no unnecessary additions, which suits the minimalist style perfectly. This is a ring that reads as versatile - it works as an everyday piece worn on its own, and its restrained character means it can also be worn as an engagement ring.

For this piece we chose an onyx with an exceptionally even, deep black colour and a clean surface free of discoloration - it was precisely this uniformity of colour that decided the choice of stone, and quality of this class at this price is becoming increasingly rare. Silver and good stones are steadily rising in price, so buying a ring like this now remains a sound decision from a pricing standpoint. It is set in refined European sterling silver 925, and the fineness confirms the purity of the alloy - free of nickel and other harmful additives, so the metal does not irritate the skin. A layer of rhodium protects the surface from tarnishing and scratches, so the shine lasts and the ring needs minimal care. The piece bears the French maker's mark, which guarantees the metal's origin. Onyx has long been associated with strength, resilience and confidence - hence its popularity in rings that carry personal meaning.

On the hand it looks best paired with soft knitwear - a thick sweater in shades of grey or charcoal creates a calm backdrop against which the onyx draws the eye with the sheer depth of its black. It also looks good in a total-black outfit, where the subtle shine of the rhodium-plated silver adds contrast without drawing attention away from the stone. The medium size makes the ring comfortable to wear both day and evening, and its simple silhouette suits hands of different proportions.
