Many of the pieces that the Queen wears on a regular basis have serious heirloom pedigrees, but she also frequently receives new items of jewelry, especially as she reaches major milestones and celebrates big anniversary. Today's piece, a lovely brooch made of tourmalines, was presented to HM by the Lieutenant-Governor of Saskatchewan.
