Many thanks Marc. I must live in another universe as, while I had heard of the unsinkable Molly Brown, I hadn't connected her with the Titanic or jewellery of note. Very interesting to read all about it.

I wonder if the concept, that the wreck is a grave site, has partially informed the thinking of the British who want to have the artefacts displayed in Belfast?

I found some more images https://www.dailymail.co.uk/news/article-2231949/Titanic-treasures-Precious-jewels-belonging-passengers-doomed-ship-public-display-time-100-years-disaster.html

While I don't know about jewels, other items from the ship are scattered throughout the world. I saw some china in a private office in Liverpool.
