The Gemological Institute of America is now offering a new service to ascertain whether small stones are in fact real diamonds or whether they are synthetic imitations, Diamond World reports cited by Israelidiamond.co.il. As of today, the GIA will allow jewelers to verify small diamonds of up to and including 0.20 carats for a relatively low fee.
The new GIA service will test both for possible synthetic origins of diamonds and for the possible color treatments that the stones may have been subjected to. The new service is currently being priced at only $12 per stone and applies to stones of colors ranging from D to Z. The 0.20 carat limit applies to all stones with the exception of black diamonds, in which case the upper limit for the service is 0.50 carats. Both loose stones and stones that are already embedded in jewelry qualify for the new service.
