This specimen is from the type locality for ALL THREE SPECIES HERE, and features rich zones of all three as well.It has prismatic orange crocoite crystals to 2 cm in length, mostly broken but nice for the color. Olive green vauquelinite occurs as chalky, green growths on crocoite. More than 200 years after these specimens were discovered, the extremely rare species embreyite was discovered on similar old specimens in the drawers of the BMNH; and then other old specimens in major holdings were re-examined. This piece has a particularly rich cluster of admittedly ugly, but mineralogically important, crystals of this more recently identified species (the minute black crystals, nestled in a vug). It is an eccentric, but very fine specimen!
