Translucent, tan, pyramidal crystals range from 1 to 7mm and are both isolated and clustered on a foliated "talc"-quartz matrix. Specimens of any quality seldom turn up today. Discovered in an erratic boulder, literally sitting in a farm field, by mineral dealers Jim and Mary Walker in the early 80's as they hiked to another locality. This single productive boulder has not been traced to its origins in the nearby mountains, or duplicated in 30 years since. These numerous, sharp, interesting crystals are truly a treasure for the serious collector. (Note: I was lucky and found one old specimen from their find in a friend's collection, which when broken open revealed these pockets inside - it had never been prepped, since the day it was collected).
