Deep broen to yellow-green Beudantite crystals on front and back on milky Quartz matrix. I believe the red is also Beudantite as it is on the red part of the matrix. Crystals to about 1mm in one place otherwise mostly about 0.75 to 0.5mm or less. Very Rich specimen. Nice historic piece with a Barstow label (see prov. tab).
