Märtha has used three, the one she usually wears, a gift from King Olav on her 18 birthday, the malthese tiara without the crosses (she might have worn it with the crosses also but Im not sure), and her beautiful wedding tiara the 2. setting of the Queen Maud pearl tiara, there are pictures of it in her tread.
The provenance of The Daisy tiara is not known, on the wedding day the former cabinett secreatry of the King said that he thought he had seen a picture of Queen Maud wearing it but he was not sure. It is from ca 1910
Here are pictures of the vifte tiara, ufortunatly it disappears in the Queens hair, She wore it once when she was very young and it looked much better, I would say it looks much more beautiful as a necklace than as a tiara.
