The Blue Hope Diamond is the most infamous diamond in the world. In 1988 it was graded by GIA (Gemological Institute of America). The laboratory stated that the diamond is a fancy dark grayish-blue hue, but in 1996 it was revised to be a fancy deep grayish-blue hue. The diamond weights 45.52 carats. The stone also exhibits an intense luminescence (which means that after being exposed to ultraviolet light, a brilliant red ‘glow-in-the-dark’ effect known as phosphorescence is produced). The color remains for some time even after the light source has disappeared. The cut of the magnificent diamond is a cushion antique brilliant with a faceted girdle and extra facets at the pavilion. The clarity given to the stone is VS1, with slight whitish graining. The Hope Diamond along with other blue diamonds get their blue color from having some amounts of boron. And because of the element boron, blue diamonds are great conductors of electricity.

The Hope Diamond was once owned by Louis XIV and was officially given the title as “the blue diamond of the crown.” During the French Revolution the diamond was stolen and ended up in London in 1830. Then, Henry Philip Hope (whom the diamond is named after) bought the stone. In contradiction to the diamond’s name, it acquired a reputation for bringing bad luck to its bearer. In fact, the Hope family who had possession of the diamond had died in poverty. Later, the diamond was taken into possession by Edward McLean. Unfortunately, he also befell a similar misfortune as the Hope family. After the unfortunate event that befell McLean estate, Harry Winston, Inc. bought the Hope Diamond and donated it to the Smithsonian Institution in Washington.
