Tourmaline is rich in inclusions, but the development of cracks has become a pain in tourmaline processing. Generally speaking, in the process of processing semi-precious stones, in order to avoid the fracture of raw materials and increase the output, glue will be filled before cutting, which is to increase the adhesion and transparency.
In particular, tourmaline, as one of the precious semi-precious stones, generally has a yield of 10-20% even after being filled with glue. If you don't pour glue, the yield may not even reach 5%.
In this way, in order to reduce the cost and improve the yield, almost all tourmalines will be filled with glue before cutting.
At present, in the domestic semi-precious stone industry, more and more glue, wax, etc. or glass are added in the processing process to reduce the cost and improve the yield.
