The Wittelsbach-Graff Diamond is displayed together with the Hope Diamond for the first time. The Wittelsbach-Graff's deep blue color, flawless clarity, and royal history make it one of the most celebrated gemstones known. Its story goes back over 340 years, and the diamond has not appeared in public for more than 50 years. Both diamonds come from India and share their rare blue color. Could they have come from the same mine? Smithsonian scientists compare the properties of both gems and explore this intriguing possibility.
