To be honest, the nature of 18K gold is also very stable. So, what are the reasons why 18K gold is so easy to fade? First of all, this is related to the environment in which you live. In the dryer areas, there will be more dust in the air, and contact with 18K jewelry for a long time will have a certain impact on it, causing some black stains on the surface to make the jewelry lose its luster. Second, it is related to some acid or alkaline substances, such as the body's sweat, or cosmetics. These materials can also contaminate the surface of the jewelry when exposed to 18K jewelry for a long time. Therefore, in the summer, jewelry is relatively frequently maintained. 100% Cotton Yarn Dyed Fabric,Yarn Dyed Cotton Fabric,Yarn Dyed Checked,Cotton Yarn Dyed Fabric Shaoxing City Yongteng Textile Co., Ltd. , https://www.yongtengtex.com
