Dark and bold, this men's ring with black onyx brings a strong, geometric accent to the hand in a modern take. The cabochon-cut stone has a deep, uniform black without streaks or flashes - as the hand turns, the onyx surface answers the light with a smooth, calm sheen and never breaks up into fragments. In old-world craft, onyx was linked to strength, endurance and confidence, which makes this signet a natural choice for a gift with character.

The stone for this piece was chosen for its even, deep colour - at this price point, it's hard to find onyx with such a uniform shade. Silver and good stones are getting more expensive, so buying a signet like this now makes sense price-wise. Refined silver of European quality, sterling silver 925, free of nickel and other allergenic metal additives, can be worn without worrying about skin irritation. The rhodium layer protects the surface against tarnishing and scratches, keeping the shine bright for years to come. The signet is stamped with the French maker's mark, which establishes the piece's origin and is registered at the assay office in France.

The big size and weight of 6.5 grams give this signet a noticeable, masculine presence on the finger. It works well for everyday wear - with a linen shirt in a natural shade, a loose-cut cotton shirt or a simple thick wool sweater. Black onyx needs no extra embellishment to catch the eye - just a gesture of the hand is enough to draw attention. This is a signet to wear without taking off, at work and after hours alike.
