One fascinating fact about Star Sapphire is that its mesmerizing asterism, or star effect, is caused by tiny needle-like inclusions of a mineral called rutile within the crystal structure of the sapphire. When light interacts with these needle-like inclusions, it creates a phenomenon known as asterism, which manifests as a stunning six-rayed star that appears to float magically across the surface of the gemstone. This unique optical effect adds to the allure of Star Sapphire, making it a cherished and sought-after gemstone for jewelry and collectors.
