Laser Drilling
Very thin straight or worm-like drill channels run from the surface to a dark inclusion. The included crystal may be bleached or partially dissolved.
01
What to look for
Very thin straight or worm-like drill channels run from the surface to a dark inclusion. The included crystal may be bleached or partially dissolved.
02
What it means
Laser drilling removes or lightens dark inclusions to improve clarity appearance. It is stable but must be disclosed.
03
Expert move
Look from several angles. A straight tiny tube reaching a formerly dark inclusion is easier to see from the pavilion side.
