3 years, 1 month ago3 years, 1 month ago@ann-embury It principally has to do with the geology of the formation you are collecting these specimens at. There are a number of different factors which could lead to a regularity in the formation and shape of crystalline minerals. A big factor is geological forces and geochemistry.
