Obsidian is made of natural glass, which is rich in mineral resources and relatively low in price. Merchants rarely make fakes, and the cost of counterfeiting is higher than its own value.

Wujin obsidian is completely gem-grade obsidian, and its output is very rare.

When the rainbow-eyed obsidian is illuminated by strong light, see if you can see it. If you can see it, it means rainbow-eyed obsidian. Because rainbow eyes are all kinds of colors, it is normal to see green eyes, purple eyes or rainbow eyes sometimes. These are all called rainbow-eyed obsidian. If the colored eyes are white, it means a little color difference. As for authenticity, there are generally no fakes, so don't worry, only the quality is good or bad. Therefore, the inspection of rainbow-eyed obsidian mainly depends on whether there are double-sided rainbow eyes, whether they are all, whether the colored eyes are smart, whether the colored eyes are pure and whether there are few defects, which will affect the quality of rainbow-eyed obsidian.
