Pete Tescione Collection Pete Tescione was an avid field collector and a part-time mineral dealer in the Tucson area. We were able to acquire 3 important lots of his field collected minerals: pyromorphite from Spain, hematite from Italy, and quartz from the Jeffrey Mine in Arkansas.

A unique “T” formed from a group of doubly terminated quartz crystals perched on the termination of a longer single crystal.
