Here's an 8-pound Brazilian nodule I purchased recently. Supposedly cut by the previous owners grandparents in the 60's or 70's.

I'd like to construct a hinged stand/mount that will hold both halves, but let you move them apart/together again (articulated). Has anyone on here done something similar or know of any off-the-shelf versions?

No, I haven't heard of it but it is a cool idea. I'm not sure how to do something like that. I guess you could do something with copper piping and a tap and die for the hinge and then construct a framework for each side to attach to the hinge half, but I think you'd be better off with some kind of spring that would naturally hold it closed unless pulled or released.
