British: The Raine Spencer Tiara. The tiara is made of diamonds set in fleur-de-lys motifs, the center of which are studded with large pearls. Raine has been photographed wearing the piece both as a tiara and a necklace. It's not clear when it was made, but the design does suggest a twentieth-century creation date. Raine did have access to both of the Spencer family's other tiaras during her second marriage, so perhaps this tiara is one that she purchased on her own after she was widowed?
