Description

Created to exacting standards, using state-of-the-art gem-lab technology and minute attention to detail, this lab-created emerald has a chemical make-up identical to the finest Colombian emeralds. Its color is a more intense green than the natural stones can offer, and it performs at the bench just as a natural stone does. Unlike natural emeralds, however, this stone is heat-resistant and can be successfully cast in place and can be fired in place in silver PMC3 at the lowest temperature schedule. Emerald is the birthstone for May.

The oval cut is an even, symmetrical shape but elongated. The arrangement of its facets is similar to that of a round brilliant, designed to maximize light and color.
