Surface may show a web-like etched texture, dull luster in recesses, or color concentrations if also dyed. Structure can look loosened compared with untreated jadeite.
01
What to look for
Surface may show a web-like etched texture, dull luster in recesses, or color concentrations if also dyed. Structure can look loosened compared with untreated jadeite.
02
What it means
Acid bleaching followed by polymer impregnation improves transparency and color appearance but greatly reduces value.

Expert move
A handheld loupe can raise suspicion, but FTIR is the standard confirmation for polymer.
