Queen Alexandra’s Collet Necklace consists of “31 graduated brilliants (five detachable) in cut-down collet settings.”1
The necklace and a matching pair of earrings made of large old-cut Golconda diamonds were given to the then Princess Alexandra of Denmark upon her marriage to the future King Edward VII by the City of London.
Alexandra wore the necklace on a velvet band as a choker and usually paired it with one or more other necklaces. The necklace was passed to Queen Mary upon Queen Alexandra’s death in 1925. Two, out of a total of eight, of Queen Mary’s collet necklaces were bequeathed to Queen Elizabeth II in 1952. This included Queen Alexandra’s collet necklace.2
