Where does the Hope Diamond come from ?

 Kollur Mine in Golconda, India.

The Hope Diamond, also known as “Le Bijou du Roi” (the King’s Jewel), “Le blue de France” (the Blue of France), and the Tavernier Blue, is a large, 45.52-carat, deep-blue diamond, and now housed in the National Gem and Mineral collection at the Smithsonian Institution’s Natural History Museum in Washington, D.C. It is blue to the naked eye because of trace amounts of boron within its crystal structure, and exhibits red phosphorescence after exposure to ultraviolet light. Hope Diamond has a long and mysterious past.
