Agate is a form of chalcedonyquartz that forms in concentric layers in a remarkable variety of colors and textures. Fire agate is an opaque, limonite-bearing chalcedony with iridescence which is created by diffraction of light by the layered structure.

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.
