The deep black of onyx in this ring absorbs light rather than reflecting it - the cabochon cut rounds the surface so the shine glides across it in a soft, matte reflection. The modern solitaire form works equally well as an engagement ring or as a solitaire worn alone on the finger - the simple band doesn't draw attention away from the stone, but presents it to the hand in a clean, minimal setting. In traditional jewellery craft, onyx was associated with strength of character, perseverance and self-assurance, which sits well with its bold, dark colour.

A piece like this - with a dense, uniform black free of streaks or discoloration - is easy to overlook, yet a second one just as clean is hard to find today. Prices for silver and good natural stones are rising, so buying at this price makes sense now. Refined silver of European quality, sterling silver 925, forms a solid base here, and the 925 fineness confirms the purity of the alloy - free of nickel and other harmful additives, so the metal doesn't irritate the skin. A rhodium layer further protects the surface against scratching and tarnishing, so the shine lasts long despite everyday wear. The metal bears the French maker's mark - a guarantee of the quality and origin of the precious metal.

This ring works well in the city - with a trench coat, a turtleneck and neutral colours such as charcoal, beige or deep navy, where the black of the onyx becomes a natural finishing touch to the outfit. It also suits simple knitwear and the elegant, everyday gesture of a hand around a coffee cup or during a business meeting. The small size of the stone keeps the form light and comfortable, while still clearly marking its presence on the finger.
