A rich, blue turquoise set in a very big ring catches the eye from the moment you walk in. The cabochon-cut stone comes from the Sleeping Beauty mine in Arizona, source of some of the most prized turquoise in the world - its even colour, free of spots or discolouration, is exactly why this particular specimen was chosen. As you turn your hand, the surface of the stone shifts gently in tone, from a deeper blue to a lighter shade, depending on the light. Its bold, modern form makes this ring equally suited as an engagement proposal or as an alternative to a classic wedding band.

Silver prices are rising, and good turquoise with such an even colour is getting harder to find, so this piece at its current price is a sound choice today. For this price you get a stone carefully selected for colour and clarity, set in solid rhodium-plated silver. The rhodium layer protects the surface against tarnishing and scratches, so the ring needs polishing less often. The metal is refined European silver, sterling silver 925, free of nickel and other irritating additives, so you can wear it without worrying about skin irritation. On the inside of the band you'll find the French maker's mark - attesting to the origin of the silver.

A ring like this looks good for an evening out, when the outfit stays simple. A little black dress or a silk blouse make a good backdrop for the turquoise's striking blue - the hand wearing the ring becomes a natural focal point, drawing the eye during a gesture, a handshake or the holding of a glass. The very big size of the stone means it works well as jewellery for special occasions, rather than for everyday wear at work.
