What Defines the Beryl Group
One mineral, many gems. Beryl (Be₃Al₂Si₆O₁₈) produces emerald (chromium-green), aquamarine (iron-blue), morganite (manganese-pink), heliodor (iron-yellow), and goshenite (colorless). Trace elements measured in parts per million create entirely different gem identities from the same base mineral.
