A cabochon-cut black onyx fills this signet ring with a deep, matte black that, as the hand turns, reveals subtle steel-grey glints across the surface of the stone. This play of light is visible only in motion - at rest the stone stays calm and dense, which suits the masculine, vintage silhouette of the ring well. Before an onyx is set, its blackness and colour uniformity are assessed - only stones free of discoloration and flaws earn a place in this design. Onyx has long been associated with strength, endurance and confidence, making it a popular gift choice for a man taking his first steps in a new professional or personal role.

The signet ring is made of refined sterling silver 925 sourced in Europe, and a rhodium layer protects its surface from tarnishing and loss of shine for years to come. The alloy contains no nickel, the metal responsible for most allergic reactions, so the piece can be worn without concern for skin reactions. Silver and quality gemstones are steadily rising in price, making a purchase at today's price a sensible decision. The piece bears a maker's mark, registered with the French assay office, attesting to the origin of the metal.

The signet ring pairs well with summer wardrobe staples - a linen shirt with the sleeve rolled up, light sand-coloured trousers or a pale blazer create a backdrop against which the black of the onyx stands out most strongly. A gesture that opens the hand, resting an arm on a table or holding a glass further shows off the stone and its shifting shine. The medium size of the signet ring means it doesn't dominate the finger, yet stays noticeable and easy to feel to the touch. It's a form that works just as well for everyday wear as for a more dressed-up look.
