Grape Agate statement piece

Grape Agate: Named After Fruit, Not Quite an Agate, Entirely Fascinating

by Laura Konst
Grape Agate looks exactly like a bunch of grapes. It is not grapes, and strictly speaking it is not technically an Agate either: true Agate is defined by concentric banding, while Grape Agate grows in rounded spherical clusters through a process called botryoidal growth. The purple colour comes from trace manganese within the microcrystalline silica.
