Opal’s unparalleled beauty lies in its almost magical play of colour. Opals have long been valued for their rare ability to capture the rainbow. In the first century A.D. Pliny the Elder wrote of opals:
“For there is amongst them the gentler fire of the ruby, the rich purple of the amethyst, the sea-green of the emerald, and all shining together in an indescribable union.”
Greg Kratch, a gemmologist and lapidary whose passion for opals is both unrivaled and contagious, developed this workshop for the Montreal School of Gemmology (EGM). Greg spent over ten years mining, cutting, and grading opals in Australia’s famed opal region of lightning ridge and has studied and worked extensively with opals from the new Ethiopian deposits.
