Antique Emerald and Diamond Brooch in Original Box - GIA Colombian No Treatment

A refined antique brooch of exceptional quality, centered by a vivid emerald-cut Colombian emerald recently certified by GIA as natural and untreated. The emerald displays a richly saturated green of striking purity, a rarity made even more remarkable by the absence of any clarity enhancement. Old-cut diamonds accent the cardinal points, extending out into delicately tapered terminals that lend the piece a graceful, elongated line. Presented in its original Mackay & Chisholm fitted case, By Appointment to the Queen, this brooch embodies the craftsmanship of early 20th-century high jewelry.
