Description

I do Sapphire is a variety of corrugating, i.e. an aluminium oxide.

It's a gem alchromatic, in fact in nature exists in many colors. The presence of iron in the form of oxide is the main cause of yellow color, although in some cases the color is caused by abnormal presence (or absence) of electrons in the crystalline reticle, called color centers.
