How to see whether the moonstone is injected with glue

Three points can be seen to identify whether moonstone is injected with glue: 1. Fluorescence. Use purple light to irradiate moonstone. Natural moonstone has no fluorescence reaction, and glue-injected moonstone has a strong fluorescence reaction; 2. Hardness, the surface of natural moonstone is not easy to leave traces, and glue-injected moonstone will leave obvious traces; 3. Boil in water. Natural moonstone does not react after being boiled in water, and the texture of glue-injected moonstone will become turbid.

Fluorescence

To identify whether the moonstone is injected with glue, you can see the fluorescence. If you irradiate the surface of the moonstone with a purple light lamp, the natural moonstone will not appear or have a weak fluorescence reaction. If the moonstone is injected with glue, it will emit a strong fluorescence reaction.

2, hardness

To identify whether moonstone is injected with glue, the hardness can be seen. Use a knife to scrape the surface of the moonstone. Natural moonstone has a higher hardness, and it is not easy to leave any obvious traces on the surface. Moonstone with glue injection has a lower hardness, and it is easy to leave obvious traces on the surface.

3, boiled

Identify whether the moonstone can be boiled with water for glue injection. Put the moonstone into a cold water pot and boil until it boils. The texture of the natural moonstone will not change. The glue-injected moonstone contains a large amount of glue-like substances, and the texture will become turbid and fade.
