My inquiry was strictly to learn if there was something available that I was
not familiar with. I have never seen coarse natrolite available. I bought one
of the Bound Brook singles (more than a decade ago?), and that is all I've seen
for large, coarse natrolite. The Russian material can be large (up to 1 m long)
but generally all the coars material is singles. These crystals in Montana (and
I don't recall what I told you) are potentially spectacular. All I've seen so
far is material weathered out lying on the surface. Hopefully we can get the
locality in production. It has the potential for producing spectacular
clusters. The largest I picked up in a radial cluster had terminated crystals a
hair over 6 inches long and 3/8 inch across. From my own collecting in
Washington and Oregon, natrolite is mostly less than a couple mm across,
dominantly needle-like and hair-like.
