We are a primary jade supplier, not a fine jewelry endpoint seller. The price of the item is the price of a jade pendant only. For the pendant holder and other accessories. We provide an alloy one as photos. So you can wear it right away. It is not really gold, platinum, or S925. Even sometimes the alloy chain has a 925 sign on it. It is not S925. Thanks. (一句话，我们是卖翡翠的，卖翡翠的。不是高端首饰终端店，物品标的价格是翡翠的，链子扣头不算进价格，白送的，我们没有金/银/白金这些五金附件送的，谢谢理解)
