My transparently paned contribution of "GLASS" for "Graphical Layer And Server Simplifier" was technically a mineral, but not a very precious one. But it was great for making windows! Too bad it kept shattering because ugly X11 was on one side of it and beautiful Lisp was on the other. But at least you can cut "GLASS" to make fake gemstones of "PASTE".
