This rose gold-plated necklace is inspired by the innovative concept of "moving crystal"; a floating round Swarovski crystal is set in a three-dimensional frame set with pavé Swarovski crystals, which can inject lively brilliance into the daytime look. Necklace materials are mainly imitation crystal and alloy. The outer layer of the alloy material is plated with precious metal, and the inner layer is a special alloy that is not easy to break. Precious metal plating mainly refers to 8 metal elements including gold, silver and platinum group metals (ruthenium, rhodium, palladium, osmium, iridium, platinum)
