This 18 carat gold and silver brooch in the form of a stylized peacock, set with 47 old-cut diamonds and 34 rose cut diamonds (circa 15 carat), all taken from the same raw material. Signed: ‘F. Boucheron, Paris’. The brooch was made by the goldsmith F. Busset in February 1894 for the House of Boucheron.  I would love to have a ziconium copy of this!
