When a light source is directed towards the stone, it reflects off these inclusions, creating a six-rayed star on the surface of the sapphire.

Are Star Sapphires Real Sapphires?

Star sapphires come in a variety of colors, including blue, black, pink, and yellow. Blue star sapphires are the most popular and are highly sought after by collectors and jewelry enthusiasts.
