China jewelry refers to some natural gems or jewelry items, the price of which is much higher than that of gold, such as diamonds, agates, tourmalines and other jewelry items, while the material of gold jewelry is relatively simple, and the price will be lower. The price of gold is open and transparent and announced every day. The profit is similar to everyone else's, so it can't be very high.
The price of diamonds is influenced by many factors, such as size, clarity, chromaticity, cutting, supply and so on. Therefore, the price of diamonds can not be understood at a glance, and the natural profit will be higher.
