Material Material: Pure brass (unplated) / Tianhe stone / pink chalcedony If you need to customize, or change the natural stone type, you can contact the designer! Brass maintenance method Maintenance: Usually wipe with copper cloth, copper oil, or with toothpaste or tooth powder. Always wipe the jewelry completely dry with a cloth after cleaning. If you do not need to wear it, it is recommended to store it in a sealed bag. There is no electroplated brass and there is no problem with fading. But brass is an unplated metal. After wearing it, it will feel more retro due to contact with sweat, cosmetics or moisture in the air. Many girls buy lol for oxidized color. If you prefer a bright color, you can follow the above instructions. I can't accept a little retro feeling, don't buy, thank you! Note Attention: 1. The goods are hand-made. The production and delivery will not start until the order payment is completed. The production time is about 1-3 working days (excluding the delivery time). Please be patient. 2. Each natural stone has its own unique texture, color and size are not necessarily the same, may contain impurities or small cracks, etc., and can not be exactly the same as the products in the photo. ⭐️If you need to modify after receiving the goods, you need to pay back and forth postage!
