 I believe that it is not right to assume that artificial rock crystal (i. e. glass) is always void of impurities. Why impurities could not be added purposely? That is true for artificial diamonds because of the way of production, but in case of glass it is perfectly possible.


Dear Giovanni,

Of course, impurities could be added purposely.
Firstly, I am assuming no one would go out of their way to do this, unless they are trying to create a special effect.
Secondly, the type of impurity introduced artificially into man-made glass are very different from the types found in natural quartz. So to add some impurities for the purpose of deception seems pointless.

Regards,
Tom
