The water tank agate identification knowledge

Identify the authenticity of the water tank agate.

It is hard to say whether it is impracticable to look closely at the handicraft carvings.

The inner wall of the water urine has blemishes (blackening) or crystal crystals, which are usually natural. This is the trace left when the agate is formed.

Observe carefully with a 10x magnifying glass, and use a knife or needle tip to describe the problem. Since the hardness of agate is 7 on the Mohs, the hardness of the knife is 5~5.5. If the false part is glued, the hardness will not reach 7, and the knife can be used. Engraved.

If conditions permit, please ask the experts for identification and ask for a gemstone identification certificate.
