This black onyx solitaire ring draws out a deep, matte black from the stone, one that reveals dark, satiny glints across its faceted surfaces as the hand turns. The minimalist band doesn't pull attention away from the stone: the line is narrow and smooth, leading the eye straight to the onyx. This is the form known as a solitaire and promise ring, simple in outline but distinctive in character. Onyx has long been associated with strength, resilience and confidence, making it a natural choice for a gift with personal meaning.

A piece like this, where the black is even and deep across the whole surface of the stone, is easy to overlook among less uniform examples. Silver and good natural stones are rising in price, and clear onyx free of discolouration is becoming harder to find, so this ring is a sensible choice to make now. At this price you get a solid choice of stone and careful workmanship, with no compromise on quality. It is set in refined European silver 925, and a rhodium layer protects the surface from tarnishing and keeps the shine for months. The metal bears a maker's mark registered with the French assay office, which attests to its origin. A pure alloy, free of nickel and other harmful additives, means the ring can be worn without worrying about skin irritation.

For an evening out it pairs well with the little black dress and a smooth silk blouse: in that kind of styling, it's the onyx that catches the eye as the hand lifts a glass or smooths back the hair. Its small size means the ring sits close to the finger and never gets in the way of a gesture. French chic favours this kind of simplicity: few elements, one striking stone, a clean line of metal. The ring weighs 1.7 g, so it's barely felt on the hand, yet clearly seen.
