Aquamarine is actually such strong protection that it protects against danger. It is a stone of courage. It helps you learn about your physical world and about yourself. It shields your aura, and it is a Throat Chakra crystal. This crystal is one of the Beryl Group, and all of the Beryls are quite special. Two Beryls are Angel Crystals--Morganite and Goshenite.
