Of foliate scroll design, collet-set with cushion-, pear-shaped, circular- and single-cut diamonds, inner circumference approximately 290mm, French assay marks for gold and silver, later fitted case stamped Mellerio. 

Provenance: This diamond tiara probably comes from the Bourbon Lignières family.

On 12 November 1927 in Lignières, France, Madeleine de Bourbon Lignières (1898-1984), daughter of Georges de Bourbon Lignières, Comte de Lignières, and Jeanne de Kerret de Quillien, married Prince Xavier de Bourbon Parme (1889-1977), son of Robert de Bourbon Parme, Duke of Parma and Piacenza and Maria Antonia de Bragança, Infante of Portugal. 

Thence by descent.
