On my visit to the Royal Palace in Kuantan to confirm the ‘discovery’ of Queen Mary’s Cartier Diamond Lozenge Bandeau last week, Queen (Tengku Ampuan) Azizah of Pahang tasked me with solving the mystery of her Aquamarine Tiara, which has a twin in Scotland.

The Aquamarine Tiara was acquired by her ‘Auntie Nora’, the then Sultanah of Johor, at Hennell in London in the 1980s, and is in a Carrington & Co case from the reign of King Edward VII, which confirms it’s authenticity, yet the question remains if this Tiara was created at the same time as the Tiara of Lady Saltoun?

The Queen and I compared the two Tiaras, and apart from the shade of the central stone, everything seems to be the same, even the cuts of the individual diamonds. The elements of the Tiara can be removed to be worn as five separate brooches, with fittings for that and a chain also in the original case, while a smaller version of the Tiara can also be created from the separate elements.It's not uncommon for there to be two identical Tiaras, but even I was surprised at the identical cuts of diamonds.

The additional Diamond Necklace was added to the base for the Wedding of the Queen’s daughter, Princess Afzan, earlier this year.
