1969 The Star of Queensland

Discovered in Australia, this sapphire becomes the largest in existence. Weighing 1,157 carats, the stone is cut by Harry Kazanjian into the famous 733 carat Black Star of Queensland, one of the rarest gemstones in the world. The Kazanjian family loans it to the Smithsonian Natural History Museum. It is displayed alongside the Hope Diamond, the largest blue diamond in the world. The priceless gemstone is eventually sold to a private collector, with the proceeds funding scholarship programs at the GIA (Gemological Institute of America).
