Treatment Disclosure

we promote full disclosure of all treatments carried out to gemstones. we strongly believe this is essential knowledge that must be passed on at every step of the chain from mining to processing to manufacturing to end consumer. That is the only way to maintain the confidence of the consumer, without which the industry doesn't survive.

we will always disclose all treatments or enhancements on all gemstones that we work with, and that we are aware of.* Fortnately, most of the time we work from rough (purchased from trusted miners and suppliers), and we control the processing of that rough including grading, sawing, preforming, cutting, and treating (if necessary). This means we are able to confidently disclose any and all treatments done to the gemstones.

as a matter of business policy we only work with
trusted suppliers and primarily with natural, untreated gemstones, as much as possible.

we use the following
enhancement codes recommended by the American Gem Trade Association (AGTA) for disclosing treatments:

N - Not Enhanced
B - Bleaching
C - Coating
D - Dyeing
F - Filling
H - Heating
HP - Heat & Pressure
I - Impregnation
L - Lasering
O - Oiling/Resin Infusion
R - Irradiation
U - Diffusion
W - Waxing/Oiling in Opaque Stones

SC - Special Care Required

ASBL - Assembled

CMP - Composite

* on the rare occasion where we are unsure about whether a treatment or enhancement has been carried out to a particular gemstone we will clearly inform our customers about this.
