Is this a gemstone or just glass

.-Sounds like calcite, a chrystalline mineral-I too think it is quartz that has colored blue. It doesnt look like a natural color.......
http://s10.postimage.org/yjfym1bzt/SN850… I bought it from a second hand-store in a bag with other stones? is it a crystal or just a piece of glass It's kinda waxy and pretty solid.

The color appears to be superficial as if someone colored it with a blue magic marker. The areas that can be seen through in the thickest part of the crystal are colorless. It could be calcite. I think I see a few of the cleavage planes. It doesn't have the yellowish ting but not all calcite does.

Edit: No, on closer examination I think it's quartz. The right end seems to be the pyramid. It appears to have gotten a bit of rough and tumble.
