Nothing says aristocracy quite like a tiara. This one is Edwardian, and offered for sale by London-based Bentley & Skinner. They describe it as, “An Edwardian diamond tiara, with foliate swags and floral motifs graduating from the centre, set with old brilliant-cut and rose-cut diamonds estimated to weigh a total of 8 carats, all to a yellow gold mount with detachable frame, (convertible into a necklace or coronet), circa 1900, gross weight 69.68 grams.”

Should you have a glam, tiara appropriate event to attend (though you could just wear it as a necklace), this will set you back£46,500.
