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.
we
will always disclose all treatments or enhancements on all
gemstones that we work with, and that we are aware of.*
as a matter of business policy we only work
with trusted
suppliers and primarily with natural, untreated
gemstones.
we use the following codes
recommended by the International Colored Gemstone Association (ICA) for
disclosing treatments:
N
- A natural gemstone processed only by cutting and polishing
E
- Natural gemstones, enhanced by trade accepted practices specific to
each gemstone
T
- Natural gemstones, treated by processes that require specific
disclosure
codes for specific treatments include:
H
- Heating
R
- Irradiation
D
- Diffusion
W
- Waxing/Oiling
O
- Oiling/Resin Infusion

information about ICA please visit their website www.gemstone.org
* 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.
