Product description

Some rare natural sapphires exhibit a star-like phenomenon known as asterism. These gems contain intersecting needle-like inclusions (often the mineral rutile, a mineral composed primarily of titanium dioxide) that cause the appearance of a six-rayed star when viewed with a single overhead light source. To cause a star, the rutile needles need to form in parallel and tightly packed groups. The reflection off of each group of crystals forms a straight line that appears to float on the surface of the stone. There are always three groups of crystals that intersect at 60-degree angles from each other. The three lines formed connect in the center to form the appearance of a 6 ray star. The presence of a star is one of the more remarkable phenomena encountered in the world of colored gemstones. This optical phenomenon is quite rare, being only found in a tiny percentage of the sapphires mined around the world. Star sapphires can occur in any color, but the most common colors are blue, black, and pink.
