Blue that keeps moving. The Blue Crystal Dangling Earrings hang a luminous blue crystal so it turns freely and changes with the light.A dangling setting matters more than people assume. Because the stone is not fixed flat against the ear, it rotates slightly as you talk and walk, so the blue brightens and deepens continuously instead of sitting at one intensity. The crystal is faceted to make the most of that, and the setting stays fine enough not to interrupt it.Why you'll love it: Free movement and sharp faceting give these a livelier sparkle than any fixed stud. A strong colour that still works with black, navy, grey and everything already in the wardrobe. Holds its finish through everyday wear, without tarnishing, dulling or marking your ears. Restocks are slow on this one, so it is worth deciding now.
