Lot Essay

The tiara is thought to have been made by E. Wolff & Co. for Garrard shortly after the 6th Duke's marriage in 1889. A painted miniature on ivory of Ivy, Duchess of Portland (1887-1982), when she was Marchioness of Titchfield, depicts her wearing the tiara and the matching stomacher brooch. Ivy was the 7th Duke's wife.

It is noted in the 1887 inventory that several of the family jewels were dismantled to construct the tiara.
