The deep blue of two cabochon-cut turquoise stones only truly reveals itself up close, when light falls across the smooth surface of the stone and brings out its rich, even hue. The earrings have a dangling, classic form - they move gently with every turn of the head, so the turquoise keeps catching the light differently and plays against the face in ever-changing ways. It's this closeness to the face and hair that makes the stone's colour immediately draw the eye of anyone you're speaking with.

The turquoise comes from the Sleeping Beauty mine in Arizona, source of some of the most prized specimens in the world - an even, pure colour free of blemishes is a rarity, and a pair of two turquoise stones this closely matched in shade is hard to put together a second time today. Silver and quality stones are steadily rising in price, so buying this pair now, at a reasonable price, makes sense. The earrings are made of refined sterling silver 925 sourced in Europe - it is the fineness mark that confirms the purity of the alloy, free of nickel and additives that could irritate the skin. A layer of rhodium protects the silver from scratching and tarnishing, so the metal keeps its shine over long-term daily wear. Every piece bears the French maker's mark, struck as a mark of the metal's origin.

These earrings pair well with a spring look - a pastel trench coat, a silk scarf tied at the neck and a light handbag in a cool shade. Hair swept into a loose bun or tucked behind the ears reveals the line of the neck and lets the turquoise take full effect against the face. Against a classic, understated outfit, this shade of blue brings a clear, fresh touch of colour.
