A Star Blue Sapphire is a rare and stunning gemstone known for its asterism, a star-like optical effect caused by aligned needle-like inclusions of rutile. The star typically features six rays and is most visible under direct light. This phenomenon enhances its value and appeal, making star sapphires highly sought after in jewelry and collections. They are often associated with wisdom and protection in folklore and are primarily sourced from Sri Lanka, Myanmar, and Madagascar.
