Let's close the theme, for it's related, I won't discuss Pss Margaret's jewelry so we can stay on topic. None of Princess Michael's tiaras, to the general knowledge, comes from a direct line of either the Windsors or the Glücksburgs (Greece / Denmark).
- The Fringe was a presente from The City of London to HRH Princess Marina of Greece and Denmark upon her marriage to HRH Prince George, Duke of Kent.
- The Festoon tiara, the one I posted before, not much is known of it. It was given at some moment to Pss Marina from her husband, Prince George.
Those tiaras were inherited by his smallest children, she didn't leave anything to her daughter (in royal circles, princesses use their husband's family heirlooms), and the lion share (or what was left of it, since Pss Marina had to sell things very early on to make ends meet), were left to Edward, her eldest.
Now, it is not that well known, but some of the jewels were sold after Marina's passing, inheritance taxes could be a pain in the a***, you see. Then, of course, she inherited a few things from Wallis, yes, that
Wallis, brooches and all. Minor things, Marina also left a few necklaces, earrings, and stuff. They also sold some, my guess is the same, inheritance taxes.
