Ruby / Fracture-Filled
The process of fracture filling ruby is a recent innovation that began around 2004. Rubies of good color, primarily from Madagascar, can be enhanced using a combination of heat treatment with lead glass. Because the refractive index of corundum and lead glass are very similar, light can travel through the stone unhindered. Fracture-filled rubies can often be bought in exceptionally large sizes that heat-only ruby would almost never be found in, and at a fraction of the cost of heated or untreated ruby. So they are of excellent value, as long as the treatment is disclosed and the price is appropriate.

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.
