Lepidolite after Tourmaline

What was once an impressive tourmaline crystal became an elestial etched lepidolite after mostly pseudomorphing. I say mostly as there are several gemmy tourmaline remnants found surficially. Wonderful luster and the original face side still has much of its tourmaline “skin”. Ex Jim and Paula Wilson
