Eyeglass chain made with natural stones, pearls, and 14KGF. 14KGF is covered with a thicker layer of gold than gold plating, making it more durable and less likely to cause metal allergies, which is recommended! Note: Not everyone is guaranteed to be allergy-free, so please wear it while monitoring how you feel. Because it is a very delicate design, there is a risk of breakage if pulled strongly, so please use it with care. Thank you for viewing.
