Along the way, the question may arise:
- How to distinguish rhinestone from ordinary glass..?.
Early indication..even in quartz, the super-extra quality, have to be "blind" or inclusions, the glass they are not..
... And, you can just hold the sharp edge of the crystal quartz glass( a very pleasant experience).... Glass will not scratch glass, and crystal will leave streaks.
But still worth looking through a quartz crystal tumbling of quartz, a piece of quartz or all that you have in the hands o the world..
When passing through natural mineral white light is decomposed into colored rays. Glass has light and remains white, which is visible to the naked eye.
