This Gorgeous 5x3mm Gem Quality Oval Genuine Chatham Cultured Ruby Weighs Between .23-.28 Ct. Individual stone weights may vary outside the average weight range, but the size of the gemstone will be consistent.
Our Chatham lab-created rubies are real rubies 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 rubies mimic the vivid pigeon blood color of the finest Burmese rubies. 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.
