TF73AL5: Very aerial growth of needle-shaped Cosalite crystals, a lead and bismuth sulphosalt rare in high-quality collection specimens. The Cosalite crystals, with good terminations and luster, are partially covered by transparent Fluorite crystals, creating an elegant contrast between the metallic acicular forms and the cubic Fluorite growths.
This piece comes from the Rock Currier collection (no. 6166) and it has been photographed and published as a reference for the Cosalite species in the magazine ‘Lapis‘ number 05/2024, page 13
