This specimen has an interesting history...Found by Louis Spalding and traded in 1990 to Bill Larsen; Bill sold it in 1991 to Andreas Guhr (Hamburg, Germany); Andreas Guhr sold it to Cal Graeber (California) in 2004.
It consists of numerous Alpine-type, gemmy, transparent, light smoky Quartz crystals with a slightly tabular habit are resting in a bed of snowy Albite. Two black lustrous Schorl crystals, one fully terminated measuring 42 x 18 mm, and the other measuring 22 mm across are nestled in the Albite. This Schorl is not terminated -- it was broken during pocket growth. Many lustrous, gemmy, red-orange Spessartine garnets, the largest measuring 19 x 17 mm provide notable accents. Small Spessartines form inclusions within some Quartz crystals.

This is the best specimen to come from the commercial mining effort completed in 2004 by John Seibel, Steve Perry and myself when I owned the mining claim. The specimen is 11.9 cm in its longest dimension, and the largest linarite is a complex crystal group approximately 4 cm in length. This one I decided to keep.
