GIA to Issue Revised Coloured Stone and Pearl Reports and Launch Report Check Enhancements

CARLSBAD, Calif. – 29 January 2015 – Effective 1 February, GIA will begin issuing revised coloured stone and pearl reports and launch Report Check enhancements. The revised reports feature improved gemstone images and language that reflects the most current gemmological terminology. Report Check for coloured stones and pearls will feature a new treatments tab, providing consumer-friendly gemmological information using text, graphics and images about any treatments detected.

Report Check Enhancements:

On Report Check, the coloured stone and pearl reports take the viewer directly to a treatments tab if relevant, which provides additional gemmological information about any treatments an item has undergone; the report data is included in an additional tab. This is available for stones evaluated on or after 1 February 2015. The image of the item will now be included with the data on Report Check. 

Diamond reports in Report Check feature plots and proportion diagrams when available for reports issued on or after 1 January 2014.

Coloured Stone and Pearl Report Revisions:

GIA’s coloured stone and pearl reports now feature a layout in portrait orientation.

A new paper will now be used for coloured stones and pearls to support higher quality photo images.

One form - a Gemological Report - will be used for coloured stones and pearls.
