Want to know whether aquamarine and aquamarine crystal are the same thing?

Aquamarine is an beryl, hexagonal and very light sky blue. Aquamarine is generally natural and has no synthetic appearance, internal cracks, impurity inclusions and other characteristics. Of course, there are many very clean aquamarine, and no inclusions can be seen with the naked eye. The identification feature of aquamarine is that "rain-like" inclusions can be seen under the magnifying glass of 10 times, which can be seen by naked eyes, usually through light.

What is said upstairs is wrong. Aquamarine and synthetic blue crystal are also birefringent, and the difference is very small, so it is impossible to distinguish them. Unless measured by a refractometer, that is, measured by a refractometer, it is not birefringence but refractive index that distinguishes them. . Conceptual confusion

The name "aquamarine crystal" is very unscientific. Many businesses try to muddle through in this way. Some stores sell aquamarine, and some stores may sell some synthetic blue crystals. The synthesized blue crystal is bright cobalt blue, which looks fake, and the inside is clean without "rain" inclusions.
