These dangle earrings pair a modern, lightweight stud line with the warm, saturated colour of turquoise. The medium cabochon-cut turquoise has a uniform, deep blue with no streaks or discolouration - a shade that turns up rarely, since only a small share of the sorted raw material from the Sleeping Beauty mine in Arizona makes it into production. As you move your head or the light changes, the cabochon catches the light differently than a moment before, and the delicate stud lets the stone sway gently by the ear.

Arizona turquoise of this quality is becoming ever harder to find, since nature itself limits its availability, and precious metal prices rise year on year. The setting is rhodium-plated 925 sterling silver, extracted and refined in Europe, coated in a layer of rhodium - a hard metal that protects the surface from tarnishing and dulling, keeping the shine bright for years. It is a pure alloy free of nickel and other harmful additives, so even with extended wear the skin has no reason to react. The silver bears a French maker's mark establishing the piece's origin, registered at the assay office in France.

These earrings sit well with a sleek hairline pulled back into a bun or with a hairstyle that leaves the neck bare - the blue of the turquoise stands out clearly against skin and hair. For a day in the city, pair them with a beige trench coat and a thin, cool grey turtleneck, where the neutral backdrop lets the stone truly shine. At 3.7 g, they wear light all day, from morning coffee to an evening out.
