Natural Stone Mini Tumble Necklace Deep Rose Quartz AA++ (Madagascar) Amethyst AA++ (Zambia) Crystal Quartz AA++ Two other colors are also available. Chain, wire, and all metal fittings are 14kgf (stamped) Total length: Approximately 40cm A very refreshing necklace has been created. I think it will brighten up your face. All metal fittings use 14kgf, so they have a beautiful, long-lasting shine and are allergy-friendly. However, it does not guarantee that everyone will be allergy-free. Please gently wipe with a soft cloth after use. It will last even longer. This is a handmade item. Please handle it gently, as applying strong force may cause damage. We have carefully crafted this item with attention to the materials. Thank you for your interest.
