This one is attributed to the Pederneira Mine. I've seen only one other specimen from this pocket, in one of the Crystal Classics cases at the Tucson Fine Mineral Gallery. I'm not sure if this was an older undocumented pocket (pre-1999) or if it was a more recent pocket found after the article was written in 2015. Regardless, it is a really cool piece! The specimen features three tourmaline crystals on a terminated quartz crystal. The termination of the middle tourmaline is partially coated in feldspar, as is the termination of the quartz crystal. The smaller crystal on the front has a flat termination with rainbow colored zoning. Acquired from Mike Bergmann at the Tucson show in 2024.
