The jewels Daisy purchased and commissioned from the talented designers at Maison Boivin revealed, in particular, her great admiration for their spectacular brooches. As one of Boivin’s most important and enthusiastic clients, she often acquired several pieces at one time: Boivin’s records show that in March 1939 she ordered ‘an orchid, a daffodil ring, a chameleon, a pair of earrings, a daisy, an arrow and two tourmaline leaves.’ Apart from the chameleon brooch, every other design was a new creation from Boivin.
