I think the reason Princess Lilian was able to sell peices of jewells, is because there is no law preventing members of the Belgian RF selling or taking the jewels to the country they were marrying in, as did the daughter of Queen Elisabeth did when she married into the RF of Italy, and Josephine Charlotte when she married into Luxemburg, and even Queen Fabiola is holding tight onto her jewels. they took with magnificent peices, it's still hard for me to see CP Mathilde with one Tiara, and no other magnificent diamonds. The only peice whicH by law goes to the Crown is the nine provinces Tiara.
