A rich and unusual mix of minerals on such a small specimen. We have small spherical druses of the rare sulfate chalcoalumite, rare silicate ajoite [not or wrongly analysed, could be a cyanotrichite-group mineral] along with brochantite on native copper and cuprite. 2 x 1.5 x 1.1 cm. Crystal Vine specimen, Sara Giller photograph.
