This engagement and wedding ring brings a modern, geometric touch to a classic form. The black onyx in a cabochon cut has a smooth, deep surface - as the hand turns, light slides across it in a narrow, silvery line, while the stone's colour itself stays undisturbed and full. The plain band keeps attention on the stone, so the whole piece sits calmly and confidently on the finger, in keeping with a modern, understated design line.

This particular piece was chosen for its uniform, deep black colour and a surface free of even the slightest discoloration. Good stones of this quality are becoming harder to find, since nature itself limits the supply of valuable specimens, and silver and precious metals have risen in price in recent years. That makes buying a ring like this today, at a reasonable price, worth considering. The base is sterling silver 925 refined in Europe - it is the fineness mark that 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 against tarnishing and scratches, so the shine lasts long and everyday care stays minimal. The French maker's mark struck on the piece attests the origin of the metal.

Black onyx has long been associated with strength, endurance and self-assurance - symbolism that many connect with the decision to get engaged or married. In summer, this ring pairs well with a linen dress in a light, muted shade or with a cotton shirt and wide trousers - the onyx contrasts clearly with white and beige, drawing the eye to the hand. The medium size of the stone keeps the design elegant rather than heavy, which works well for everyday wear as a wedding band.
