The Federal Trade Commission (FTC) requires the disclosure of any treatment done to a natural gemstone when it is non-permanent, or requires special care to retain the benefit of the enhancement, or if the treatment has a material effect on the value of the gemstone.
How should these treatments be communicated? Ask you dealer about the stone and the codes-
N = not enhanced
D = Dyeing
HP = Heat & Pressure
O = Oiling/Resin
SC = Special Care
ASBL = Assembled
B = Bleaching
F = Filing
I = Impregnation
R = Irradiation
W =Waxing/oiling in Opaque Stones
CMP = Composite
Ask a lot of questions before buying and make sure you have a disclosure.
