Platinum 900 K18 Diamond, 0.20 carat per ear 0.40 carat total for both ears The post is foldable, allowing it to be used as an earring when extended and an ear clip when folded. It also has a silicone cushion, designed to prevent pain even after long periods of wear. The images from the third one onwards were taken under orange lighting, so the color is poor, but the actual diamonds are clear and beautiful like the first and second images. I only used them once, and they have been stored away ever since. They will be delivered in a case and box.
