Lab-Grown Alexandrite 5mm Round Faceted Gemstone

Created to exacting standards, using state-of-the-art gem-lab technology from high quality material grown in the United States, this lab-grown alexandrite has a chemical make-up identical to the finest natural alexandrite. The gemstone provides more consistent color tones while refracting clean bright hues, especially under florescent light. It performs at the bench just as a natural gemstone does but, unlike natural alexandrite, this lab-grown gemstone is heat-resistant and can be successfully cast or fired in place. Alexandrite is the birthstone for June. Round-cut gemstones are highly popular and the most commonly available. Rio round gemstones are calibrated for size and hand inspected to ensure maximum attractiveness.
