A cool, blue flash plays across the surface of the moonstone with every turn of the hand. The cabochon cut brings out this adularescence - light gathers beneath the domed surface and shifts gently as the hand moves. The minimalist solitaire setting doesn't distract from this effect - the smooth band leads the eye straight to the stone. Moonstone has long been associated with intuition and inner awareness, and has also been kept as a companion for moments of meditation.

Before it is set, every moonstone is assessed for colour and clarity - what matters is the strength of the sheen and the purity of the structure, free of cloudiness. Silver and good natural stones get more expensive year on year, so buying now makes sense price-wise. Refined silver of European quality, whose 925 fineness confirms the purity of the alloy, is free of nickel and harmful additives - it doesn't irritate the skin. A rhodium layer protects the surface against tarnishing and scratches, keeping the ring's shine bright for years to come. The French maker's mark on the metal confirms its origin.

This big, striking cabochon sits well on the hand for a meeting in the city - under a sand-toned trench coat or a simple turtleneck in cool grey. A neutral outfit palette only highlights the play of light within the stone, and the blue flash draws attention without any further adornment. The ring weighs 4.8 grams, so it sits lightly on the finger despite the stone's clear presence. It suits everyday, simple outfits where one strong detail is what counts.
