Internal Laser Drilling is a clarity treatment that uses a laser to enlarge existing cleavages or create new ones, providing a path for a bleaching solution to dissolve the inclusion.

• A. A clarity treatment that uses a laser focused on or near an inclusion to enlarge existing cleavages or create new ones, providing a path for a bleaching solution to dissolve the inclusion.
• B. A method to physically drill holes for mounting in jewelry
• C. A whitening treatment that bleaches the entire diamond
• D. A technique to measure color using lasers

Answer: (A)

Internal laser drilling is a clarity treatment aimed at reducing the visibility of inclusions by creating a narrow channel from the surface to the inclusion so a bleaching solution can reach and alter the inclusion. The laser is delivered to or near the inclusion to enlarge a natural fracture or to create a new pathway, allowing the bleaching agent to dissolve or lighten the inclusion and improve the stone’s apparent clarity. This isnates the description as the correct choice, because it focuses on a clarity enhancement that uses a laser to access an inclusion for bleaching, not on mounting holes, whitening the entire diamond, or measuring color with lasers.
