We make every effort to create our products with the utmost care, but please refrain from purchasing if you do not understand that they are handmade. If you would like to change from earrings to clip-on earrings, please let us know in the comments. Changes after purchase are not possible as the price will be adjusted to include the cost of the replacement parts. Length: 3.5 cm The clasps and wires of these earrings are made of surgical stainless steel, which is hypoallergenic. Those with sensitive skin or metal allergies can use them with confidence. Natural stones are a gift from nature. They are not artificially made minerals, so there may be cracks and inclusions (such as the original rock) and variations in shape and pattern. We hope you understand the nature of natural materials.
