What this service covers.
Dye treatment involves introducing colouring agents into a gemstone’s surface-reaching fractures or porous structure. The laboratory examines specimens under magnification and fibre-optic illumination, supplemented by spectroscopic analysis to detect characteristic dye signatures.
Dye detection is particularly relevant for jadeite, chalcedony, pearls, and porous ornamental materials where treatment may not be immediately apparent.
Included in this service
✓ Microscopic examination under multiple lighting
✓ Fibre-optic illumination analysis
✓ Spectroscopic dye signature detection
