Sapphire Lab-created alexandrite made from corundum lot

Sapphire Lab-created alexandrite made from corundum is not true alexandrite (a variety of chrysoberyl), but rather synthetic sapphire treated to mimic alexandrite’s color change. This material is often marketed as "lab alexandrite-like sapphire" or "synthetic alexandrite sapphire."

Color-change sapphire typically shifts from blue or bluish-purple in daylight to purple, violet, or reddish-purple under incandescent light
