Some rare sapphires exhibit a color change under varying lighting conditions. Color change sapphires are typically blue in natural light and purple under incandescent indoor light. Color changes may also be pink in daylight to greenish under fluorescent light. Some stones shift color well and others only partially, in that some stones go from blue to bluish purple.

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.
