A moonstone cabochon brings a soft, cool flash of blue to this ring, appearing and disappearing with every movement of the hand. This phenomenon, known as adularescence, shows to best effect in the smooth, domed form of the cabochon cut, where light glides across the surface and reveals a blue glow just beneath it. The plain, modern band keeps attention on the stone, and the slender solitaire silhouette works equally well as an everyday ring to mix and match with other jewelry or as a wedding ring. Moonstone has long been associated with intuition and inner awareness, and was traditionally present at moments of reflection and meditation.

Each cabochon for this solitaire has been individually reviewed and selected for clarity and the intensity of its shimmer, so at a relatively accessible price you get a stone of clearly above-average quality. Silver and good natural stones rise in price year after year, so buying a ring like this today remains a sensible choice. The rhodium coating on the silver is a hard, scratch-resistant metal that protects the surface from tarnishing and dulling, keeping the shine bright for years. The silver is stamped with the French maker's mark, attesting to its origin, and the refined European 925 silver, free of nickel and other harmful additives, can be worn without worry of skin irritation.

For an evening out, this ring pairs well with a little black dress and a silk blouse. Against a muted, dark outfit, it's the blue flash of the stone that catches the eye with every movement of the hand. It's worth skipping extra bracelets or heavy earrings on such occasions, so the cabochon stays the centre of attention. The medium size of the stone means the ring sits comfortably on the hand without feeling heavy. At 3.6 grams, it wears lightly through a whole evening.
