Cristal Non-Piercing Labia Jewels. Turn your body into a work of art with exclusive erotic jewellery by European designer Sylvie Monthule. Handcrafted in Paris with only the highest quality materials, these jewels are designed to heighten the sensitivity of the labia. Made from genuine 18k gold plated metal with genuine Swarovski crystal accents, these are luxurious and non-piercing. Available as a set of two, they easily open to gently clasp the labia, giving the appearance of a piercing.
