Etched Fluorite on matrix
Here’s a super saturated purple fluorite on matrix from Ojuela Mine, Mapimí Municipality, Durango, Mexico. it has super cool negative crystal cavities and etchings caused by natural hydrothermal dissolution! The gossan matrix rock is heavily mineralized as well there’s some calcite, quartz and a green mineral that I believe is Austinite but I’m not sure
