1. With the help of strong light

Ordinary obsidian without rainbow eyes, you just need to illuminate obsidian with a strong flashlight. The real obsidian is not black under strong light, but dark brown or dark brown. Fake obsidian is usually made of glass. As long as we hold it up and shine it under strong light, it will show glass blue.

Rainbow eye (light) obsidian, that is, you can see the green/purple/yellow reflection when you look at it under strong light, under the sun, or under the flashlight of your mobile phone. Among them, the surface of rare quality obsidian is light red, the surface of ghost-eyed obsidian is light blue, and the surface of ghost-eyed obsidian is mostly red and blue, so the quality is very rare.

2. See if it is polished.

Real obsidian jewelry needs to be polished after being pressed and carved in a steel mold, so the fine outline will be damaged to varying degrees, and the concave-convex three-dimensional effect will not be three-dimensional after being released from the mold. The fake glass products are molded by casting with a mold at one time, and do not need polishing, so the fake glass products have a clear outline and a delicate concave-convex feeling.

Open it all.
