Internal Laser Drilling (LDH) Inclusion Photography
Internal Laser Drilling (LDH) inclusions are man made flaws that resulted laser-drilling that is done to remove large inclusions in a rough stone, and the drilled passage does not breach the cut diamond's surface.
All of the microscopic diamond inclusion photography on this page was generously contributed by the AGSL gemological testing laboratory in Las Vegas, Nevada, and is reproduced with their permission.
