What is the purpose of laser drilling?

• A. Using a concentrated beam of laser light to reach a diamond's dark inclusions and disguise or eliminate them.
• B. A method to cut the diamond with long pulses
• C. A measurement of laser energy
• D. A technique to polish facets

Answer: (A)

Laser drilling is used to improve a diamond’s appearance by targeting eye‑visible dark inclusions. A focused laser bores a tiny channel from the surface to the inclusion, allowing the processor to modify or bleach the inclusion so it becomes less visible. This can make a diamond look clearer without changing its shape or facets. It’s not about cutting the diamond, measuring energy, or polishing facets, and the resulting drill hole may be left as a small mark or filled later.
