A 7 mm sharp crystal of leadhillite with classic greenish color, perched in a protected vug in cerussite matrix. Although small, this is a SUPERB, incredibly sharp crystal for the locality. Beer Cellar leadhillites are one of those holy grails of a US collector. I have seen 6 in my life, perhaps, and owned 3 (all thumbnails, in tthe past). Ex ER Chadbourn Collection.This piece came to me with the George Feist collection recently, and was his best quality specimen of the old material dating to the late 1800s and very early 1900s. The Feist collection was known as a very significant US locality suite for MidWest minerals.
