Famous Diamonds Chart
Akbar Shah
An Indian diamond which became famous during the days of the Mughal Empire. A diamond with a roughly pear-shaped outline and random faceting, including two Persian inscriptions, the first reading "Shah Akbar, the Grand King, 1028 A.H." (the letters mean Anno Hegirae). The second inscription read "To the Lord of Two Worlds, 1039 A.H. Shah Jehan". The diamond was reportedly part of the original Peacock Throne. Purchased in 1886 in Istanbul by London merchant George Blogg, who re-cut it from 116 carats (23 g) to a pear-shape of 71.70 carats (14.34 g), thus destroying the historic inscriptions. Blogg was the last known owner and the stone's whereabouts are presently unknown.

Blue Heart DiamondBlue Heart Diamond
The Blue Heart weighs 30.82 carats and has a rare, deep blue color. The Parisian firm Atanik Ekyanan of Neuilly cut it into a heart shape in 1909 or 1910, and this date raises the issue of whether the rough stone came from Africa or from India. In 1910 Cartier purchased the diamond and sold it to an Argentinean woman named Mrs. Unzue. At the time, it was set in a lily-of-the-valley corsage and remained so until Van Cleef & Arpels bought the gem in 1953. They exhibited it set in a pendant to a necklace valued at $300,000 and sold it to a European titled family. In 1959 Harry Winston acquired the gem, selling it five years later, mounted in a ring, to Marjorie Merriweather Post. Mrs. Post donated the Blue Heart to the Smithsonian Institute in Washington D.C., where it remains to this day.
