On August 21, 2009, during the Diablo 3 Heroes and Monsters and Heroes panel in BlizzCon, the development team stated that they changed the Wizard's stone armor visually, since it was hard to notice on the class due to the wizards thin and sleek profile and that it didn't support the goal of making the wizard a "Lightshow". It's assumed it works the same way, but they have also decided to change the name of the spell, which they haven't thought of yet. Visually, it has become a purple/light blue crystallized armor (see image on right) and is now easily detectable.
