Answer:
The answer is: Hexagonal crystal system
Step-by-step explanation:
Beryl is a cyclosilicate that exists in the form of hexagonal crystals. It is a naturally occurring mineral that is a major source of Beryllium and is a known carcinogen.
It belongs to the hexagonal crystal system of the hexagonal crystal family, which is one of the six main crystal families in the crystallography.
Therefore, Beryl is part of the Hexagonal crystal system.
