Made to resemble a natural emerald, this lab-created stone features a deep emerald-green color. Offered at an attractive price point, this stone is a great value—ideal for multi-stone designs and vintage-style jewelry. Unlike natural emeralds, 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.

Sometimes called an 'emerald cut,' the octagon cut has a rectangle shape and cut corners. Its facets are concentric planes that resemble stair-steps around the circumference of the stone, above and below the girdle.
