What this service covers.
Clarity enhancement involves filling surface-reaching fractures with oil, resin, or polymer to reduce their visibility. The laboratory uses FTIR spectroscopy and UV fluorescence to identify the presence and type of filler material.
The degree of enhancement (none, minor, moderate, significant) is assessed where applicable, following internationally recognised grading standards. This information is critical for accurate disclosure and pricing.
