A friend was digging at this site in New York a few weeks ago
and brought this chunk of vein for me.
It is a pay to dig site on the Bower Power's Farm in Peirrepont, NY.
There is much information to be found by Google and here
is one link; http://www.geologicdesires.com/uvites%20from%20pierrepont.htm
My friend said the collecting has been pretty hit and miss for the past few years
but he said he hit it at just the right time this time and loaded up some nice material.
It is some very interesting material and, apparently, the debate continues as to what to call it.
For years it was called Uvite, with some wanting to call it Dravite.
Now, it seems, Dravite, or Dravite-Uvite, is politically correct.
Like many minerals the only way to tell for sure which it is is to have it chemically tested.
And if you go to the trouble of having that done you could end up with one of four possibilities.
Dravite, Uvite, Fluor-Dravite, or Fluor-Uvite.
Mindat has a good breakdown of the different possible tourmalines present.
Anyway, he said he knew I would want a chunk with lots of matrix to pick at
and he was right. I love it!
here's a pic of side A. I have done considerable picking and cleaning
of the limonite-goethite oxidation around the one large crystal on this side.
