"The famous blue-gray diamond currently housed in the Smithsonian Institution in Washington, DC, was believed to be cut from an enormous stone bought in India by Tomas founder and diamond hunter Jean-Baptiste Tavernier. The stone Tavernier brought back from India was 115.16 carats and cut down for the French king Louis XIV to a sparkling rock of 67 carats. The Hope Diamond is 45.52 carats. Which begs the question--what happened to the missing carats?"
