Item Description

A good specimen of Tephroite and Willemite from the famous Franklin mining district. The piece comes from the Pat Gross and Rich Kosnar Collections, and remains in Pat's original micro-mounting box. The piece features small brown/black Tephroite with prismatic Willemite on matrix. I have photographed the piece under the microscope to better illustrate its quality. For rarities collectors, or those who love minerals from Franklin, this is a great opportunity to acquire a seldom seen Tephroite for your collection. It should be noted that Sterling Hill is actually the type locality for Tephroite, not Franklin.
