Few People Know Diamonds are found a variety of colors naturally. Some colors more common than others. The worlds most famous diamond, the hope diamond, is a rare natural blue color (on display the the Smithsonian Museum in DC)
The world’s first diamond color-grading system dates back to sixth-century India. The system was based on the country’s ancient class structure. Members of different status levels, or castes, were permitted to own and wear only diamonds of a specific color. Thus, diamonds served as a badge of rank.
While fancy color diamonds have traditionally been a small part of the diamond business, their popularity and availability have grown in the past several decades. Learn more about natural color diamonds here.
