Approximately [GH VVS] Star sapphires are a type of sapphire that displays a phenomenon known as asterism, which is the appearance of a six-rayed star-like pattern that appears to float across the surface of the stone when it is viewed from certain angles. This effect is caused by the presence of inclusions within the sapphire, such as tiny rutile needles, that reflect light in such a way as to create the star-like pattern.

The beauty of star sapphires lies in their unique appearance and the way the star seems to shimmer and dance across the surface of the stone as it is moved. They are also highly prized for their deep blue color, which is often compared to the color of the night sky.
