I don't think this is real quartz. However, there is a place in the world for glass pebbles. This one is almost entirely clear - far too clear to be quartz. I managed to scratch it with some known quartz, which doesn't bode well for it. Nevertheless I do not want it, so here we are.

This is one glass pebble which is trying really hard to be quartz. It was bought as part of an old crystal collection which I had to take whole. One thing you can be sure of here at TSC is that we always tell you the truth. This pebble has no place in your crystal ocllection but it makes good home decor.
