This is a small specimen but contains excellent crystallized Bigcreekite in a "veinlet" about 1mm. The Bigcreekite is colorless and striated.
Bigcreekite is only found in California.
This specimen as well as most of the others in the Special Edition was identified by the expert on the barium-silicates, the late Robert Walstrom.
