beryls
Hexagonal crystal gems
Beryls is the plural of beryl, a mineral that occurs as hexagonal crystals and serves as the source of several gemstones.
Pure beryl is colorless, but trace elements create prized varieties: emerald (green from chromium), aquamarine (blue-green from iron), morganite (pink from manganese).
The museum displayed beryls from mines across three continents.
