Cu₃₁S₁₆

Massive, dark gray colored Djuerelite with a high, silvery luster is found in several places on this specimen in a matrix composed of massive Quartz and greenish colored Muscovite crystals. There is a green to blue/green alteration product around the Djuerelite. There is a similar specimen posted on mindat where this is listed as Langite, but in places, the color is too green and might possibly be Malacite which is also listed on mindat for the location, with a question mark. Specimens from the location are seldom available.

Condition: Good

Flaws: Essentially massive material.
