Internal laser drilling
Use of a laser to heat an inclusion in a diamond, causing it to expand and create fine surface-reaching fractures, which in turn allow for a chemical treatment of the inclusion, generally changing the appearance of the inclusion from black to white (CIBJO 5.46). The treatment must be disclosed (CIBJO 4.2.2).
