Description

This one is weird. Blue Wulfenite on limonite-coated Quartz from Ojuela Mine. I am not sure if the etched surface and the color of the Wulfenite is caused by a natural solution or a man made failed cleaning experiment. The core of the crystals is yellow. Got that one with an Ojuela lot from past Tucson show..
