[Rockhounds] Ad- Blue/green Apophyllite

[Lawrence Rush]

I recently got a dozen pieces of an unusual blue-green variety of 
Apophyllite. Although these are from Jalgoan, India, they do not look at all 
like the usual blocky form of Apophyllite from there. These are different in 
color, and are arranged in a parallel habit, with the prism being elongated 
and frequently twinned. Apparently they never occur as single crystals.The 
matrix (Natrolite) is mamillary and stalagmatitic.  My Indian friend who 
sends me minerals from there says that these are occasionally found there 
and prized by the miners for their color and gem-like appearance.

I would appreciate any any comment on these odd crystals from any 
mineralogists in the group (and also anyone interested in buying any, of 
course!).
