Star Sapphires are beautiful and mesmerising gemstones that show a distinct star ray across the face of the stone. Star Sapphires are always cut into a Cabochon shape with a high dome. This is the only way that the shining star will be seen from the stone.

The star in star Sapphires is caused by a phenomenon called Asterism. When viewed with a single overhead light source star Sapphires will show a six rayed star pattern. This pattern is caused by microscopic inclusions that reflect the light.

Star Sapphires naturally occur in a hexagon, six sided crystal. When the microscopic inclusions grown inside the Sapphire, they tend to grow from each corner of the hexagon. You will notice that star Sapphires always have six rays. This is because of the natural hexagonal crystal structure of Sapphire.

When selecting star Sapphires to purchase it is important to understand what increases value in a stone. Firstly, the most important part of star Sapphires is the star. A very sharp and well defined star is hard to find, so a perfect star in a stone will increase the price.

The color and clarity of star Sapphires has a major influence on the overall price. A stone with a very transparent body is extremely rare and will fetch a high price. The best star Sapphires will have a blue transparent body with a nice deep blue color and a sharp and vibrant star. These types of stones are extremely rare and can fetch tens of thousands of dollars.
