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.

Ashberg DiamondAshberg Diamond
It is said that this amber-colored, cushion-shaped diamond weighing 102.48 carats, was formerly part of the Russian Crown Jewels. It must have been a late addition to that collection because the stone bears all the characteristics of one from South Africa. In 1934 the Russian Trade Delegation sold the diamond to Mr. Ashberg, a leading Stockholm banker. The Stockholm firm of Bolin, former Crown Jewellers to the Court of St. Petersburg, mounted it as a pendant. In 1949 the Ashberg was displayed, mounted in a necklace containing diamonds and other gemstones, at the Amsterdam Exhibition, the aim of which was to attract new workers to the diamond industry. Ten years later the Bukowski auction house in Stockholm put the Ashberg up for sale but it failed to reach its reserve and was withdraw. Then its owner succeeded in selling the gem to a private buyer whose name was not revealed. Finally, in May, 1981, Christies auctioned the diamond in Geneva where once again it failed to reach its reserve and was withdrawn.

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.
