The stunning rainbow effect of mystic quartz is the product of a new high tech enhancement process applied to colorless stones such as quartz and topaz. The technology, known as thin film deposition, was pioneered by a company called Azotic Coating Inc. The color, brilliance and clarity of the final product depends very much on the quality, cut and polish of the original gemstone, and we use only first quality quartz for our mystic quartz.
man their gems are pretty good, and the prices aren't to bad either, I like checking out hte gems on there website, beceause the pictures of the gems are taken pretty well, and you can see the table, and the facets.
I love gemselect and I have bought a fair amount from them. The only complaint I have is not being able to save gems. I have a lot of projects so i am in the market for a lot of different gems and it's so disappointing to have to delete them all just to purchase one or two that I have saved in my cart.
