The American Gem Trade Association (AGTA), has proposed a list of “codes” to use as product labels, indicating possible treatments.
- ASBL – Assembled product
- B – Bleaching
- C – Coating
- CMP – Composite materials
- D – Dyeing
- F – Filling
- H – Heating
- I – Impregnation
- IMIT – Imitation
- L – Lasering
- N – Natural
- O – Oil/Resin Infusion
- R – Irradiation
- SYN – Synthetic
- U – Diffusion
- W – Waxing/Oiling
AGTA also suggests that consumers should still receive information on enhancements in “plain language,” not simply codes. However, hopefully, these codes will promote a “uniform and consistent communication language.”
Note: Nveloop GMS customers following AGTA standards can easily update disclosure codes (also known as CDS Common Disclosure Codes) in “Settings”. If you need assistance, please don’t hesitate to call our support team.
