Star sapphires contain intersecting needle-like inclusions that cause the appearance of a star-shaped pattern when viewed with a single overhead light source. Convinced there was an asterism hidden within the rough stone, Kazanjian cut the stone as an oval cabochon, sacrificing 423 carats of material, in order to reveal a six-pointed star. Kazanjian studied his new purchase for two months before deciding how it would be cut. Kazanjian agreed to pay $18,000 (about $185,000 in today's dollars). This got the attention of Armenian-born jeweler Harry Kazanjian, who traveled from Los Angeles to Queensland to make a deal. In 1947, gemstone aficionados soon learned that the massive gem-quality black sapphire was for sale. The struggling miner realized that the family's doorstop could be worth a small fortune if the right buyer could be found.

Eventually, Harry, learned that sapphires did, in fact, come in nearly every color of the rainbow (except for red, which is called 'ruby').

The dad, Harry, was a pioneering miner of the central Queensland gem fields, but apparently didn't realize that sapphires could present themselves in this unique black color. Although the palm-sized stone weighed an incredible 1,156 carats, it spent the next nine years languishing as a doorstop in the Spencer family home. When the world's largest gem-quality star sapphire gem was found in 1938 by 12-year-old Roy Spencer in Queensland, Australia, the boy's dad dismissed the stone as an enormous black crystal and threw it aside. September's birthstone is sapphire, so today we present a little history about a famous sapphire that nearly lost its chance to shine.
