Prehnite on calcite, Brandberg, Namibia
description: T
2 5/8" talll
This piece consist of a vivid green crystal of prehnite and a colorless and transparent rhombohedral crystal of calcite on a matrix which is covered by small colorless crystals of quartz. I have seen no other specimen like this from Namibia although I have seen much larger prehnite specimens. It is a unique piece.
