The brooch is part of the Cambridge Emerald Collection:

Queen Elizabeth II wore the Cambridge Emerald Brooch with the smaller Diamond Pendant from the Nizam of Hyderabad Necklace, instead of the large pear shaped emerald drop.

Queen Elizabeth was only seen, one time, in public with this combination in the 1980th with her Corgies at Sandringham.
