First of all, your treasure is not fake, because it is so bad that it can't be sold. There are no cracks when you buy it because jade is cooked in the first step, with the aim of making the surface brighter and filling tiny cracks. Wax boiling is a unified behavior of the industry and does not belong to counterfeiting. Yellow cracks are collectively referred to as black cracks in the industry. The main reason is that you don't take it often or leave it for too long, and the air enters oxidation. This usually happens when there is not enough water or cracks. This is a common phenomenon. If you buy a bracelet as perfect as possible, of course, the price will be more expensive than this.
