Sharp woodhouseite crystals to 4 mm or so drape all over the quartz points here, makig nthis both a significantly rich and a beautiful specimen. I have seldom seen such good examples larger than a thumbnail, of this rare species named after the noted mineralogist Woodhouse. The mine is now close dand defunct, and this material is impossible to find easily on the market. As this is a large and somewhat showy piece, I attach value to it beyond just as a representative of the species.
