This green stone is described by my stone supplier in Vancouver, as brucite. It has a rather wonderful array of green to bluish gray colours in it and can at times be reasonably translucent.
It is quite a lot harder that alabaster and grinds better than it chisels as the crystals can tear out rather than cut cleanly. Also the hardness varies hugely within the rock.
My aim is to get as big a triangulate shape hollowed out within the piece as possible. The limitations are on getting the tools in there to do it. This is the easy part done.
