Cullinan VI and VII

The Cullinan VI diamond is marquise cut and weighs 11.5 carats. King Edward VII had given to his queen consort, HM Queen Alexandra, who had it set into her Regal Circlet in 1908.

Currently, it is set into a brooch and suspends from another diamond cut from the Cullinan rough, Cullinan VIII.

This diamond is often confused with Cullinan VII as they are both marquise cut. The difference between the two stones is that Cullinan VI is a longer, more pointed style of marquise cut, and the Cullinan VII is slightly smaller and more rounded marquise cut.

This photo shows the difference in shape and size from the Cullinan VI and VII respectively.

The Cullinan VII weighs 8.8 carats and was placed in a necklace along with cabochon emeralds and presented to HM Queen Mary by the Maharanee of Patiala on behalf of the ladies of India to mark the first visit to India by a British Queen-Empress. Queen Mary had the necklace altered to match her Delhi Durbar Parure. Both the emerald and diamond drops are detachable.

The Cullinan III and IV - aka The Cullinan Brooch

The third and fourth stones cut from the Cullinan diamond were fondly known as ‘Granny’s Chips’. Granny was Queen Mary, queen consort to George V and the grandmother of HM Queen Elizabeth II. She had the Cullinan III and IV set into the finial and band of her crown temporarily, for her husband's coronation on June 22, 1911.

These two stones could be removed from the crown and worn in unison as a brooch with the 63.6 carat, cushion cut Cullinan IV on the top and the 94.4 carat, pear shape Cullinan III on the bottom. Queen Mary wore this brooch quite often and usually to important functions, including the marriage of her granddaughter Princess Elizabeth in 1947. This brooch is now part of the personal jewellery collection of HM Queen Elizabeth and is not part of the Crown Jewels. Due to the weight of the stones when worn in the brooch style, it is not worn very often.

The current value of this pair of diamonds is £ 50,000,000 or $100,000,000.
