Thank you for viewing! These are simple earrings made with natural champagne quartz. The beauty of the champagne quartz creates an elegant, mature charm. The ear hooks are made of surgical stainless steel, but you can also request a change to screw-back earrings (surgical stainless steel). Please let me know. 【Notes on Purchase】 〈About Surgical Stainless Steel〉 Although the metal fittings are made of metal allergy-friendly materials, allergic reactions vary from person to person. Please be aware that we do not guarantee that all people will not have an allergic reaction. 〈About the Product〉 The photos may look slightly different from the actual product depending on the lighting and the device you are using. Also, while each piece is carefully made, it is not as strong as a mass-produced product, so please handle it with care. Thank you for your understanding.
