Well, making them in a lab gives an opportunity to give the stone the trait we people see as desirable: clarity, size and colour.

A stone like this in natural quartz would cost over 100$ in it's own right, like this it's more like 10$.

There are giveaways, but usually you need a spectrometer if it's a good replica. This stone is a giveaway with the tint, it's a bit too "sun yellow".
