Item Description

Mirror-bright, metallic foil-like, golden-bronze astrophyllite plates on pegmatitic quartz matrix from a famous Colorado locality - St. Peters Dome. Astrophyllite is a RARE titanium silicate and this is a large crystal cluster of the species and locality. Ex Mullane Collection and certainly an older specimen, as it comes with a faded, The Bradleys label, calculated 1950-51 according to the Mineralogical Record label archive. I have only seen 3 of these, ever. Valued $500
