You can sleep better tonight knowing that this one will probably NOT come back to haunt us. Re-reading L Field's book I find that the gems from a tiara
which sounds like the loopy thing were from De Beers, given in 1901. The piece wasn't seen after 1910. QME used these diamonds along with others in the collection to make that other one that I don't like. (see page 33 of the 1987 hardback edition).

It has been interesting reading the book again as many of the items mentioned were not illustrated but are available on this or other sites. Also, the photos now on-line are much clearer than in the book.
Ahh technology ...
I wonder though, as she describes The Duchess of York's wedding tiara as being borrowed from a friend of the Ferguson family (see page 36). Is that right ?
