@Iwillwait those are blue Fluorite cubes with some calcite and quartz. Lots of iron oxide stains. Brought home a lot from New Mexico a couple years back.
@Iwillwait Some of the individual crystals I found down there are really cool too but will fade in the sunlight. Found this one on the surface sitting under a mesquite
Some miner way way back tossed it out. They were looking for the lead ore Galena associated with these minerals. Had a very high silver content to it. For every ton of lead ore it was 40% silver
@Iwillwait Some people do cut them into gemstone jewelry but Fluorite is pretty soft. Fractures easily. Sure does have some really cool colors though. Any color you can think of..
