Modern and minimalist, this black onyx ring is built on pure geometry of form and the stone's deep, matte darkness. The faceted cut draws out delicate glints of light along the edges rather than a showy sparkle - it's a play of surface, not a dazzle. Two cubic zirconia stones set beside the main stone add a subtle, cool contrast without drawing attention away from its depth. A specimen of onyx like this, with an even, saturated black free of streaks, is easy to overlook - a second one of similar quality is hard to find afterwards.

Refined European silver 925 forms the base of the ring, and the 925 fineness attests to the purity of this alloy - free of nickel and other additives that could irritate the skin. Rhodium plating protects the surface from tarnishing and scratches, so the ring needs less everyday cleaning and keeps its shine for longer. Onyx has long been associated with strength, resilience and confidence, making this ring a natural choice for an engagement or as a wedding ring. The French maker's mark struck on the piece attests to the origin of the metal. Silver and good stones are rising in price, and specimens with onyx of this purity are becoming rarer - today is a sensible moment for such a purchase.

On the hand it looks best paired with soft knitwear - a grey jumper or a roll-neck in ecru tones, where the cool black of the onyx and the silvery rhodium stand out clearly. A monochrome palette - grey, beige, black - lets the stone lead the eye without unnecessary contrast. Its medium size and weight of 1.5 grams mean the ring sits lightly on the finger, never getting in the way of everyday hand movements. It's a form that works just as well as an everyday piece of jewelry as it does as a symbolic gesture for an engagement.
