being VERY careful, take a needle(like from a needle & thread) And SLOWLY chip off the clay.Even if the clay is hard, this trick should work

P.S: Make sure not to chip off any lapis luzuli.

Thanks Toby and my apologies for not getting back sooner. For some reason I was unable to get on the site. When I first asked my question I had only begun to try and clear off the "clay" like material. It is hard with a vitreous luster seems to break in a conchoidal manner. It is up to a 1/4 inch in thickness and way too hard to stick a needle into it. I'm sure it encases lapis lazuli which is about 1/2 clear of the grey rock/mineral whatever! The specimen is 5"x4"X11.5". Any other ideas?
