Beautiful Malachite. Like green marble. The detailed info. is below. When I first went to The Gemological Institute of America & we were doing gem identification, one of the first things that we were told is Never do a sight identification (deciding what something is without testing) unless it is malachite. For some reason every time I see malachite I remember this.
1970s Astro Pop---OMG, I LOVED these things! But they were amazingly dangerous when they were licked to a sharp point---betcha they're "outlawed" by the FDA today, since kids these days don't know enough NOT to stab themselves with their candy. ;)
