This gemstone is a 3.66-carat natural sapphire exhibiting a beautiful blue color. It’s cut into an oval cabochon, which is ideal for showcasing the star phenomenon. The dimensions, 8.70 x 7.78 x 4.93 mm, define the oval cabochon shape.

A key feature of this sapphire is its natural, untreated state. It has not undergone any heat or other treatments, indicating that its color and clarity are entirely natural. This adds to its value and desirability.

The most prominent characteristic is the presence of asterism, or the “star” phenomenon. This optical effect, caused by light reflecting off needle-like inclusions within the gemstone, creates a star-shaped pattern on its surface.
