01
What to look for
Color concentrates in cracks, pits, drill holes, porous zones, or grain boundaries. Surface color may look unnaturally even or vivid.
02
What it means
Dyeing artificially improves color in porous or fractured materials. Durability varies and disclosure is required.
03
Expert move
Inspect drill holes and fractures first. Dye often pools where the material is damaged or porous.
