(1) [see]
Natural crystal in the process of formation, is often affected by the environment always contains some impurities, observation of the sun, can see the light evenly tiny horizontal stripes or catkin substance. And fake crystal with defective crystal design and scales smelting, after polishing processing, color copy, no catkin stripes, material.

(2) [tongue licking]
Even in the hot summer dog days, natural crystal surface with his tongue, also have the feeling of cold and cool. Fake crystal,, no cool feeling.
