    $\begingroup$ Looks like rose quartz from central/ Black Hills near Custer/Pringle SD. $\endgroup$ – Gary Kindel Mar 29 '16 at 0:12

It certainly looks like rose quartz, but best to try a quick test. Chip off a small flake and see if it is hard enough to scratch glass. If it does, then it's almost certainly quartz. The translucence and vitreous fracture are also giveaways.

  • $\begingroup$ +1 on the vitreous. There should also be some concoidal fracture. $\endgroup$ – winwaed Jan 15 '16 at 14:02

Looks like rose quartz. I have a smaller version of this but the color is not as consistent as yours. here is an image of rose quartz

Pretty nice chunk of rose quartz. It is probably from some interesting pegmatite vein, where could be more interesting minerals or even pockets with crystals.
