Yes, some people just wear brooches so naturally, like scarf people too (both, which I look like I'm trying too hard when I wear either).
I love the Cambridge emeralds too. I am a big colored gemstone fan, especially emeralds.
I am not sure where you live, but if you ever go to London, Queen Victoria's emerald tiara is now on display.
There was an exhibition that displayed her emerald set. I flew to see it (I live in the US), and it was magnificent. The tiara and other pieces (not all) are now on "permanent loan" at Kensington Palace in case you are interested. It is worth going to stare at. I toured the palace and went back twice (before lunch & after lunch) to stare at those emeralds; the security guard probably thought I was planning a heist.
Here is a link that announced the exhibition I went to that shows the gorgeous tiara. The emerald tiara and a few other pieces are still on display.
