All of the Lepidolites in this Daily Five are from the Dr. David London collection. London wrote the book "Pegmatites", and is considered an authority on the formation of these interesting and incredibly mineralized geologic deposits. 

This specimen, cataloged with his number, is a larger piece rich in fine grain rich, deep purple-lilac Lepidolite. There are a few tabular crystals of white Spodumene, another lithium mineral, attached on the sides.
