A turquoise cabochon opens this ring with an even, calm blue tone, free of streaks or discoloration. Before being set, every stone was assessed for colour purity - hence this smooth, saturated surface with no hint of grey. The turquoise comes from the Sleeping Beauty mine in Arizona, source of some of the most prized specimens on the market. The smooth cabochon cut doesn't scatter the colour across facets but concentrates it in one clear plane, visible at a glance on the hand. The modern, slim band brings a lightness to the form - it can be worn as a solitaire ring or as a promise ring, in either case with the same simplicity of line.

Good turquoise in this depth of colour is becoming harder to find, and prices for silver and gemstones keep rising season after season - which makes now a good time to choose it. At this price you get careful stone selection and solid craftsmanship in the setting, with no compromise on either. Rhodium plating protects the silver from tarnishing and keeps its shine despite everyday wear. The metal is refined silver 925 of European quality, free of nickel and other allergenic additives - it can be worn without concern for skin irritation. The piece is stamped with the French maker's mark, which guarantees the origin of the metal.

Day to day, this ring sits well with a soft, chunky-knit sweater, especially in monochromatic outfits - beige on beige, grey on grey. The turquoise blue then brings life to a calm look without stealing all the attention. It also works well with a simple shirt with a rolled-up sleeve, where the hand stays in focus. The small size of the stone and the 2.1 g weight mean the ring sits lightly on the finger and doesn't get in the way of everyday movements.
