Distinguish between true and false sheep fat white jade

1、? Look at the structure

Sheep fat jade can be identified by looking at its structure. The real suet jade is observed under the microscope, and it can be seen that tremolite crystals are intertwined in fibrous, felt and fluffy structures, which is a unique structural feature of suet jade, but other jade crystals do not have this feature.

2. Look at the luster

The luster of natural suet white jade is very moist, not that kind of strong glass luster, that is to say, the surface reflection of suet white jade is not very strong. This is because there are small bumps on the surface of Hotan suet jade, similar to ground glass, which can be seen with a magnifying glass of 10-20 times. Sometimes you can see the lines left by hand grinding in a certain direction.
