A tiny, surface-reaching tunnel produced by a laser light beam is called?

• A. Kaps
• B. Laser Drill-hole (LDH)
• C. Kerf
• D. Lamproite

Answer: (B)

When a diamond’s internal inclusion is targeted by a laser, the result is a tiny tunnel that reaches from the surface into the stone. This specific term is Laser drill-hole, often abbreviated as LDH. It describes the deliberate laser-made channel used to access and typically treat or bleach inclusions, which is distinct from other types of cuts or formations. The other options don’t fit this description: a kerf is simply the width of a cut made by a blade, not a laser-driven tunnel to an inclusion; lamproite is a rock type associated with diamond-bearing geology, not a feature inside a diamond; kaps is not a standard term used for surface-reaching laser channels.
