This Gorgeous 4.0mm Gem Quality Round Genuine Chatham Cultured Emerald Weighs Between .18-.22 Ct. Individual stone weights may vary outside the average weight range, but the size of the gemstone will be consistent.
Our Chatham lab-created emeralds are real emeralds with the same chemical, physical and optical properties as their natural counterparts. They are grown by the flux method, which means they grow in the same crystal structure as natural mined stones. These gorgeous lab-created emeralds mimic the slightly bluish-green vivid color of the finest Colombian emeralds. Gem quality means there are no inclusions visible to the naked eye. Comes with a small 4-color warranty card, which also certifies Chatham-brand authenticity.
