Gemological Institute of America (GIA) is extending the usage of its 4Cs application (app), which it launched last year for the iPad. The service is also available for iPhone usage now, and is planning to make this app accessible on additional smartphone devices.

The application is free and focuses on interactive modes to deliver its information. The application offers insight into the 4Cs (Color, Clarity, Cut and Carat weight) of diamond quality, GIA’s grading scales, how diamond grades affect value, the origins of the carat system, information on fluorescence, diamond treatments and synthetics, as well as a “My Diamond Wish List” for consumers.

A direct access to GIA Report Check, a secure online database of GIA grading reports is also offered.
