A moonstone cabochon is encircled by a halo of fourteen small cubic zirconia stones, giving this ring a distinctly classic, vintage silhouette. The cabochon cut doesn't flatten the stone - it draws out a wandering blue flash that appears with every movement of the hand and vanishes as the light shifts. Jewellers call this phenomenon adularescence, and in ancient cultures moonstone was associated with intuition and inner awareness, seen as a symbol of quiet reflection.

For this piece, a stone with an even, clear colour was chosen, free of cloudiness that would dull its clarity - hence the impression of a consistent, uniform glow across the whole surface of the cabochon. Good moonstones are becoming harder to find, and silver has been rising in price for some time now, so a piece this refined at this price is a sound choice today. The ring is made from refined European silver 925, free of nickel and other harmful additives, so it does not irritate the skin. A rhodium layer protects the surface from tarnishing and dulling, so the metal's shine lasts through daily wear. The French maker's mark struck on the piece attests to the origin of the metal.

On the hand it works best with an all-black look - a black turtleneck or a simple long-sleeved top creates a backdrop against which the stone's blue flash catches the eye immediately. The big size of the cabochon and the halo of cubic zirconia stones show to good advantage with the gesture of a hand raising a glass or smoothing the hair - it's this movement that reveals the full play of light. At 4.1 g, it sits confidently on the finger without feeling heavy. The classic form means this ring can be worn both in the evening and in a more understated, toned-down daytime look.
