The Black Star of Queensland, is a black sapphire, and was the world’s largest gem quality star sapphire until The Star of Adam was discovered. The stone was reportedly discovered by 12-year-old Roy Spencer in the mid-1930s in the Queensland gem fields. Roy showed the stone to his father who assumed that it was merely a large black crystal. Not realizing the value of the stone with its rough exterior, the family used it as a doorstop in their home for over a decade, until they took a closer look and discovered the gem hidden within.
