Stuart Tiara can be worn in three versions. It could be worn in a smaller version (with the Stuart centre diamond as a pendant to a brooch or corsage-de-devant). It definitely is one of the most historic jewels present in today's royal families. It was worn by Mary Stuart, Princess of York as Princess of Orange and later Queen of England, Scotland and Ireland. Only the large pear shaped (Stuart) diamond on top belonged to Mary II Stuart. 1897, German Jeweller Schurmann in Frankfurt.
