Shuibeijin is a new type of gold jewelry, which is made of many materials and mainly contains copper, zinc, aluminum and lead. We can't judge its authenticity directly from its appearance, but we need to compare the gold composition to judge its authenticity. If the content of these components in water shell jewelry gold is the same as that in metal gold jewelry, it can be considered that water shell jewelry gold is real.

Therefore, if you want to know whether the water shell gold is real gold, it is best to test it through a professional testing institution.
