The Queen Is a Real Work of Art in This Puzzle

"Reigning Queens," featuring Queen Elizabeth II and Queen Margarethe II of Denmark (both by Andy Warhol), are on display at Christies Auction House in London. In the portrait, Her Majesty is wearing what looks to be the Hyderabad necklace, a wedding present given to her in 1947 by the Nizam of Hyderabad. The Duchess of Cambridge has worn the piece on a few occasions as well. The Queen is also wearing the Vladimir tiara in the portrait which, according to the Court Jeweller, has both emerald and pearl settings.
