This big ring set with two moonstones pairs a bold, modern form with a subtle play of light. Each cabochon holds a blue flash that appears and vanishes with the slightest movement of the hand - the phenomenon of adularescence, characteristic of moonstone. The double stone arrangement gives the ring a layout reminiscent of a promise made not with one symbol, but two at once. In many cultures moonstone has been linked to intuition, inner awareness and moments of meditation.

A matched pair of moonstones with such similar colour and clean, deep sheen is rare to find - a second, equally striking specimen is easy to miss. Silver and good natural stones are rising in price, so buying now makes financial sense. The ring is made of refined sterling silver 925 of European quality, coated with a layer of rhodium that protects the surface from scratches and keeps its shine over time. The pure alloy, free of nickel and other allergenic additives, lets you wear it without worrying about skin irritation. The metal bears a maker's mark registered with the French assay office, which attests to its origin.

This big, striking shape works well for a meeting in the city - paired with a trench coat, a simple turtleneck and muted, neutral tones, the stone's blue flash draws the eye without excess. On the hand, in the gesture of a handshake or adjusting a scarf, the moonstone reveals itself gradually, depending on the angle of light. It is a ring that pairs well with a simple look, where the rest of the jewellery stays to a minimum.
