That is so interesting The Royal Watcher! The floral tiara looks like a piece from an earlier era. What a shame there aren't images of earlier Countesses wearing tiaras. I wonder if the one worn by Virginia Cherrill was a Jersey family piece?

When Photobucket deigns to allow me to upload and post the photo of Margaret, Countess of Jersey wearing the diamond cross, I will do so. I'll try again in a minute.

Oops!! I wrote Viscountesses Hinchingbrook above. I had confused the two threads -- the one about the jewels of the Earls of Jersey's family and those of the Earls of Sandwich. I have now deleted the reference to the Viscountesses of Hinchingbrooke from this post, as the Viscount of Hinchingbrooke is the heir to the Earl of Sandwich, not the Earl of Jersey.
