American 14K gold filled uses a mechanical method of high temperature and high pressure to press a 14K gold layer of no less than 5% onto a metal substrate, and uses the good ductility of pure gold to permanently combine the pure gold layer with the embryo layer. Therefore, American 14K gold filled is much more anti-allergic than ordinary gold-plated products and is not prone to allergies. ❤**Tips and maintenance methods**: Natural crystals contain natural cotton wool, ice cracks, black spots, and color bands. These are marks given by nature after billions of years of baptism. They are important characteristics of natural Gemstone crystals and are normal phenomena. · It is normal for natural pearls to vary in size and have growth lines and spots on the surface. ·American 14k gold is not afraid of water, you can wear it in the shower, contact with clean water can achieve self-cleaning and extend the color retention effect, avoid alkaline products such as sulfur soap, and should not contact cosmetics.
