We had known for some time that Queen Alexandra died without a will, but we learned in Roberts that HM left specific instructions for the distribution of her jewels written in the photographic inventory.
So that is the note that would have been written c. 1920 by Queen Alexandra - bequeathing the tiara to Princess Victoria. Queen Mary later made notes in Queen Alexandra's inventory detailing which pieces were given to Princess Mary, the Queen Mother, and others. Queen Mary also added the note that Princess Victoria disposed of Queen Alexandra's tiara. Unfortunately we don't know where it went.
