Deep, dark blue lapis lazuli meets a simple, modern band of rhodium silver in this ring. Two cabochon-cut stones are set close together, their surface catching subtle flashes of light with every turn of the hand - navy in one light, deep cool purple in another. The form of the ring is light and understated, so all the attention stays on the colour of the stone. Lapis lazuli was once associated with idealism, intuition and harmony, which brings this shape close to the idea of a promise made to another person.

A matched pair of two stones with such an equally intense, even tone and clean texture is easy to overlook - finding a second piece of similar colour depth is difficult today. Silver prices are rising, and good coloured stones are becoming rarer, so buying at this price makes sense now. The band is made of refined European silver 925, coated with a layer of rhodium - a hard metal that protects the surface from tarnishing, dulling and scratches, so the ring needs less cleaning and keeps its shine for longer. The pure alloy, free of nickel and other harmful additives, does not irritate even sensitive skin. The metal bears the French maker's mark - confirmation of its origin, registered at the assay office in France.

This ring feels at home in summer, on a hand emerging from the sleeve of a linen dress in a light, broken shade of white or sand - the blue of the lapis lazuli then stands out clearly and draws the eye. It also suits a simple cotton shirt with rolled-up sleeves, for wearing it every day, not just on special occasions. The medium size works well for slender to medium-width fingers, and its weight of 3.7 grams keeps the ring light in everyday hand movement.
