A simple gem test to identify a true Sea of Cortez Pearl from all other varieties of pearls. It involves the use of a long-wave Ultraviolet (UV) lamp.
The Cortez Pearl glows red under this light, truly a unique attribute of this special marine gem.
The video also includes the effect of long-wave UV light for other pearls: Tahitian Blacks, White & Golden South Sea Pearls, Akoya and Freshwater pearls.
The video has been updated from the original low-quality format to HD in order to keep up with the times. Hope you enjoy the upgrade in quality.
