This kind of jade inlaid with gold is very common in the market. In China, stones with tremolite content above 98% are called Hetian jade, not jade produced in Hetian, Xinjiang in a narrow sense. Gold is also real gold, but it is made of gold foil. One gram of gold can press out at least 0.5 square meters of gold foil, and this kind of gold inlaid jade can be made into hundreds of pieces, so the cost is very low.

This price is not expensive. You get what you pay for. The white material you described is probably caused by too much jewelry glue, which is a normal phenomenon. One copy is not allowed to be returned.
