GIA issues low-cost identification service

GIA (Gemological Institute of America) has introduced a low cost identification option in its Quality Assurance services. This new service is being offered for diamonds 0.20 carats and under and will be made available from July 1, 2012 onwards. There has been a growing need from jewellers to avail of low cost identification methods for undisclosed synthetic diamonds.

GIA’s new service will include the following features:

-It combines screening for synthetics with detection of permanent color treatments for natural stones, providing greater assurance for dealers, retailers and the public.

-The cost for Diamond Dossier® grading reports for stones 0.29 carats and below has been reduced by 10 percent.

-It is designed to randomly screen parcels of small diamonds

- The service cost is $12 per stone

- The service is applicable for examining D-to-Z diamonds and colored diamonds up to 0.20 carats, and black diamonds up to 0.50 carats.

-Based on the examination, GIA will issue a statement that the stone is synthetic or natural and – if natural – whether any permanent color treatments have been applied.

- GIA will accept both mounted and loose stones for examination. However, mounted stones are more difficult to examine and it may be necessary to remove diamonds from the setting for testing.

The Diamond Dossier includes an assessment of a diamond’s 4Cs – Color, Clarity, Cut and Carat Weight.

- A microscopic laser inscription of the report number is inscribed on the diamond’s girdle, as an added security feature.

-All stones submitted for GIA grading and identification services will continue to be screened for synthetics and treatments as part of the grading process.

The cost-effective service reinforces GIA’s overall mission to ensure confidence in the diamonds that are ultimately purchased by the public.
