The Jubilee

Weight: 245.35 carats

The Jubilee is a beautiful colorless cushion-shaped diamond with a weight of 245.35 carats. It is the 6th largest diamond in the world. The original rough stone, an irregular octahedron, without definite faces or shape weighed 650.80 carats and was found in the Jagersfontein Mine towards the end of 1895.


A consortium of London diamond merchants acquired the Jubilee and sent it in 1896 to Amsterdam where it was polished by M.B. Barends, under the supervision of Messieurs Metz. First, a piece weighing approx. 40 carats was cleaved; this yielded a fine clean pear shape of 13.34 carats which was bought by Dom Carlos I of Portugal as a present for his wife. The present whereabouts of this gem are unknown.


During the cutting it became evident that a superb diamond of exceptional purity and size was hidden in the raw. This large piece was polished and in honor of Queen Victoria’s celebration of her Diamond Jubilee (the 60th anniversary of her coronation) named Jubilee.


This also marked the introduction of the so called Jubilee cut. It combined the characteristics of both the brilliant and rose cuts in that the table is replaced by eight facets, meeting in the center, the total number of facets being increased to 88. This cut was short-lived and is not often encountered today.


In 1900 the consortium displayed the Jubilee at the Paris Exhibition where it was one of the centers of attention. Shortly afterwards Sir Dorabji Jamsetji Tata bought the diamond. He was an Indian philanthropist and industrialist who laid the foundation of his country's steel and iron industry; these and cotton mills created by his father formed the cornerstone of modern India's economic development.


Sir Dorabji Jamsetji Tata died in 1932. In 1935 his heirs sent the Jubilee for sale to Cartier, who in December of that year mounted it in a display of historic diamonds. Cartier first offered the stone to the Gaekwar of Baroda who opted not to buy the diamond. In 1937 Cartier sold the Jubilee to M. Paul-Louis Weiller, the Paris industrialist and patron of the arts. The diamond's former setting was changed into a brooch with a number of diamond baguettes, resembling either a six-pointed star or a stylized turtle.


Mr. Robert Mouawad has since bought the Jubilee which is now the largest gem in his great collection. It has been graded as E-color, one grade away from completely colorless, and VVS2 clarity.
