From Ursula's site:
In the swedish magazine SVENSK DAMTIDNING, in the numbers of the spring 1956, some articles about the memories of Crown Princess Cecile of Germany (1886-1954) are on public.
The articles mention that the Crown Princess left her jewels to her chauffeur Mr Otto Groha.
She wrote her last wills on May 2nd 1952 and January 29th 1954. On October 21st 1955 a law court annulled her last will.
Mr Otto Groha became forced by the court to return back to Prince Louis Ferdinand (1907-1994) a diamond diadem with 15 stones of 13,9 carat and about 2300 smaller brilliants. [I wonder if this is the Faberge or the Meader?]
Other jewels belonged to the Crown Princess which was mentioned in the articles are
* Pear shaped drop sapphire, she got from her husband (which she wore in her deLaszlo portrait)
* Famous Romanov emerald worth 300.000 swedish crowns (belonged to her mother)
* Small bow brooch of platinum and brilliants, also from her husband
