These are obviously fake, but I've been asked how they are made. Are the drusy crystals formed on them in a vacuum or are they natural?

What is the process by which they are colored?

The drusy crystals are most likely natural. As for the color...yeh. Probably not natural, but how they do it?

There were a number of threads about this in the past, here are some links to some of them, found in the fakes and frauds forum, there could be more.

I think it may be that those specimens have been grown in a lab.
