OMR10 Powellite
Nasik Area, Maharashtra State, India
5.7x 3.9x 2.8 cm
$0

A ball-shaped cluster of pointy powellite crystals, with a bit of matrix.  Powellite is one of the most sought after minerals from the Deccan plateau-- unlike most of the zeolite species that are also found there (stilbite, heulandite, etc.) this species has never been found in any appreciable quantity.  With that said, these days, you would probably see a higher asking price in the room of an Indian dealer in Tucson, if they had a specimen in the first place.  This piece comes from an old collection.

As a side note, powellite is not a zeollite-- it is a calcium molybdate that forms a solution series with scheelite.  

There are saw marks around the back and back-facing edges.
