Cross Stone or staurolite

I’m interested in getting one of these stones, preferably not
completely removed from its support. It is supposed to *protect its
wearer from shipwrecks" and I’d like to give it, as is, as a gift. So
I’m looking for a piece that is still imbedded somewhat, so its
closer to being a pebble than a spiky piece. Anyone have a good
source…? Should a specimen the size of a penny really cost fifty
dollars (yes, its cheaper than flying across the country and finiding
one on my own). Also thanks everyone for the hydro-torch responses…
sounds like it won’t necessarily make my life easier or less toxic in
the long run! Iris in San Francisco
