Thanks MarcA! The jewels, which I have never seen before, are very interesting. If I get time later today I will see if the UK press has anything about her wedding presents. It is possible that, at least, some of the jewels may have belonged to her husband's family. The first time I ever really read much about Princess Charlotte was in
Purple Secret by Warren, Hunt and Rohl
