Lab can accurately assess more pearls, more quickly on a daily basis
(CARLSBAD, Calif.) - GIA (Gemological Institute of America) has announced significant advancements in its pearl testing process. Highly advanced micro-CT X-ray units that produce high-definition 3-D images of individual pearls have been installed after months of tests and evaluations. These new units enable GIA to rapidly gain fully rotational 3-D images of the internal growth structures of pearls in just 15 to 20 minutes; older units take 3 to 5 hours or more. This new technology enables GIA laboratories to assess much larger groups of pearls more quickly and in greater detail than any previously employed technology.
