Hi OmerH - this has always been a bit of an intriguing point for me. We all know about the jewels that Diana, PoW got from the Queen for her wedding as well as from the QEQM. Sophie, Countess of Wessex, received the tiara from the Queen and a set of clips from QEQM. However Sarah seemed to have never received anything with any family connection from the royals.

I've always thought is strange or perhaps that jewels were received/given but never publicly worn or acknowledged.

However I think in this case Sarah, DoY maybe wearing lent or borrowed pieces or perhaps even giving a jeweller or dealer advertising.
