[QUOTE="shivan, post: 283435, member: 194"] Looks different cleaned up. The bottom photo looks like quartz or a feldspar, but in the second and third photos there seems to be a more platy cleavage or crystal growth. Along the broken edge in the last photo, are there many straight edges or pieces that flash in the light, or does it seem more like broken glass (sharp, jagged, uneven edges). If it is a calcite, marble or limestone it should be relatively soft, give it a soft scratch with a nail or knife and see if a mark is left. [/QUOTE]
