Natural star ruby is a captivating and rare variety of ruby that exhibits a unique star-like phenomenon known as asterism. This striking gemstone is highly prized for its deep red color and the mesmerizing star pattern that appears to float on its surface when viewed under a direct light source. Star rubies are not only beautiful but also highly valued for their rarity and distinctive optical effect.
Typically exhibits a deep red to purplish-red color, though the exact hue can vary. The asterism appears as a six-rayed star that seems to glide across the surface of the stone when moved under a light source. The star is best seen in cabochon-cut stones, which are polished with a smooth, domed surface. The star effect is caused by the presence of needle-like inclusions of the mineral rutile, which are aligned in a specific pattern.
