Laser Drilling
la·ser dril·ling | ˈlā-zər dri-liŋ
verb
A technique used to enhance a stone's clarity by introducing bleaching or other enhancing agents
Laser drilling is a process that allows a diamond to be enhanced for greater clarity. The technique involves introducing bleaching or other enhancing agents to the stone. A laser drills nearly microscopic holes no wider than a strand of hair into the stone, deep into the inclusion. Through this hole, the inclusion can be removed by applying high heat or injecting certain chemicals like acid that dissolve it. This process is most commonly used to remove obvious and glaring inclusions that reduce the clarity of the diamond significantly, but can be used to address most inclusions. The result is often an increase in clarity by one grade.
