This Gorgeous 8x6mm Gem Quality Octagon Emerald Cut Genuine Chatham-Created Cultured Blue Sapphire Weighs Between 1.73-2.11 Ct. Individual stone weights may vary outside the average weight range, but the size of the gemstone will be consistent.
Our Chatham lab-created blue sapphires are real sapphires 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. 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.
