Description

This magnificent specimen, host several outstanding colorless tabular khademite single crystals and clusters of a considerable size for this species.
Khademite comes from the exceptional discovery of sulphates made a couple of years ago at Monte Arsiccio but the samples found, of this rare species, were very few (I think in the order of 20 or 30 in all) The largest are clearly visible at naked eye in the photos but, in addition  to those, there are many other groups scattered here and there.
I don't know finds in the world with crystals of this size and quality, so they are probably the best khademite crystals ever found.
Also present on the sample there are beautiful clusters of single crystals of  coquimbite dark brown crystals of römerite, few krausite and silky white clumps of halotrichite.

"Personal Selection" - Hardly repeatable!
