This Gorgeous 5x3mm Gem Quality Marquise Genuine Chatham-Created Cultured Color-Change Alexandrite Weighs Between .19-.23 Ct. Individual stone weights may vary outside the average weight range, but the size of the gemstone will be consistent.
Our Chatham lab-created alexandrites are real alexandrites 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 amazing lab-created alexandrites exhibit phenomenal color change from vivid teal under natural light to reddish-purple under incandescent light. 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.
