One of my favourite things in life is haute jouillerie, particularly tiaras. Not, I add sadly, that I own any, but that I adore tiaras and diadems, with any other sparkly jewellery coming a very close second in my affections, is usually clear to anyone who meets me and talks to me for more than five minutes. A passion, I tell you, and passions are not to be denied.

I was very sorry not to get to Paris to see the Cartier exhibition there before it ended. Very sorry. The best I can offer is this little glimpse of the heaven I was denied.

Enjoy it.
