Heating beads is a very common form of enhancement and is used to affect desired alterations of color and/or clarity. Heating can also be used to lighten or darken a stone. Heat is one of the conditions that cause gems to form, whether in the ground or in a lab. Heating occurs during natural gem formation. But heating applied to the stone after gem formation is an enhancement. Beads are dyed with the introduction of coloring agent into a gemstone to give it new color, intensify present color or improve color uniformity.   

The source of these beads is Brazil and they are cut, drilled and polished in China.
