What is “laser drilling”?
Laser drilling is a diamond enhancement technique whereby a laser is used to drill into an inclusion. The dark inclusion is then either vaporised by the laser or leached out using a variety of agents (hydrofluoric acid, argon, gas, etc.) and a trail of a white cavity is left. This treatment must always be disclosed to the customer. DiamondExchange does not offer ‘laser drilled’ diamonds.
