A cabochon-cut black onyx set in a simple, modern solitaire mounting draws the eye with its deep, matte black colour. The smooth cabochon cut doesn't chase flashes of light in the stone but instead highlights its uniform, velvety surface - onyx doesn't dazzle with brilliance, it plays on calm and focus. In ancient cultures this stone was linked to strength, endurance and self-confidence, which pairs well with the ring's minimalist, geometric form.

A piece like this - free of flaws, with an even, deep colour - is easy to overlook among hundreds of others, yet a second stone of the same intensity is hard to find afterwards. Silver and good natural stones rise in price year after year, so buying at this price makes practical sense today. The ring is made of refined European sterling silver 925, coated with a layer of rhodium - this metal protects the surface against tarnishing and scratching, so the shine lasts long without extra care. The alloy contains no nickel, so wearing the ring causes no allergies or skin irritation. The piece is signed with the French maker's mark - a legally protected mark registered at the assay office, which attests the metal's origin.

In spring it looks good on a hand emerging from the sleeve of a pastel trench coat, next to a silk scarf tied around the neck and a light-coloured handbag held in hand. The black of the onyx creates a clear contrast with the delicate tones of the outfit and draws the eye with every gesture. It also works well with a simple sweater and jeans, when the hand is meant to stay the centre of attention. This ring, weighing 2.6 grams, sits lightly on the finger despite the stone's striking character.
