This little sweetheart is up for auction next month.
The tiara has 13 saltwater pearls - six button shaped ones ringed with diamonds and seven pear-shaped pearls dangling from tear-drop diamond surmounts.
It was owned by Hannah Primrose, a socially and politically active heiress, born into the powerful Rothschild family. She reputedly became the country's richest woman when her father died in 1874, leaving her the sum of two million pounds, properties including a turreted mansion in Buckinghamshire plus a huge stash of jewels.
Four years later she married Archibald Philip and became Countess Rosebery and Christie's Auctioneers believe the owner of the tiara with matching brooch and bracelet. Her jewells apparently rivelled some of the crowned heads of Europe.
There were some very snotty remarks about Hannah's weight in the comments section of the Daily Mail (yes, my dirty secret, I read it) but I think she looks serene and lovely. Perhaps because I have a feeling that she looks a lot like me only well dressed and much better jewelled.
