The present lot is accompanied by Cartier's original design drawing and a report from GCS stating that the diamond weighing 16.12 carats is N-R colour, VS1 clarity. Report number 79193-16, dated 20 December 2018.
The design of this flower brooch is very similar to the Williamson diamond brooch in the Royal Collection (RCIN 200146, see de Guitaut, C., 'Diamonds: A Jubilee Celebration', London, 2012, ill. pp 100 - 103), which represents a jonquil flower and features a flawless pink diamond, weighing 23.60 carats. The original rough was extracted from the Mwadui mine in Tanzania and given to Princess Elizabeth and Prince Philip as a wedding gift by Dr John Thorburn Williamson.
In 1952, the Royal couple commissioned Cartier to create a floral setting and Frederick Mew was responsible for the design. It was not until the 1940s, that Cartier produced more naturalistic interpretations of flowers, with Frederick Mew in London and Peter Lemarchand in Paris leading the way (see Nadelhoffer, H., 'Cartier', London, 1984, p.187). Mew was a gifted designer and watercolourist adept at drafting realistic studies of flowers. The remaining baguette, brilliant and marquise-cut diamonds were also gifted to Princess Elizabeth by Dr Williamson for setting the stem, petals and leaves and the brooch was completed in the Queen's coronation year. The Cartier design in the Royal Collection is a clear derivative of the brooch illustrated here, which features a large diamond as the principal stone with openwork petals and a more elaborately realised stem.
