Please look under the "Remarks" field in the listing which mentions which certificate is accompanying this particular gemstone. The certificate clearly mentions the carat weight, measurements, etc along with the confirmation that the gemstone is unheated / untreated. If you would like to have a certificate for a stone which does not come with a Free Certificate, just send us a message to know the extra cost. However, there is no import duty on gemstones in the USA, Europe and Canada. In other countries you may be looking at around 1% of the declared value for loose gems.
