This 3.21 carat unheated Thai green blue sapphire is a natural corundum gemstone featuring a refined oval cut that enhances brilliance and depth of color. Exhibiting an elegant blend of green and blue hues, this sapphire displays subtle color shifts under different lighting, a highly desirable trait among collectors and fine jewelry designers.

Sourced from Thailand, a region historically renowned for producing high-quality sapphires, this gemstone is completely unheated, meaning its color and clarity are entirely natural and untreated. Unheated sapphires are increasingly rare and sought after for their authenticity, long-term value, and collectible appeal.

The oval cut offers excellent light performance while providing versatility for custom jewelry designs, including engagement rings, cocktail rings, pendants, and heirloom pieces. With good transparency and balanced proportions, this gemstone is ideal for both contemporary and classic fine jewelry settings.
