Attended a Black tie event hosted by the TVe global sustainability awards at the BAFTA HQ in Picadilly, London.

My chameleon necklace was auctioned, outstripping Philip Treacy's famous Ascot hat.

The evening was chaired by Mr Oliver Rothschild, the newly elected chairman of TVe, the scion of the Rothschild dynasty.

We were in a queue near the cloakroom and he complimented me on the chameleon necklace I was wearing!

I thanked him sweetly but did not know he was Mr Oliver Rothschild. Later when I saw him up on the stage, I was quite chuffed.

I related the incident to my friend Mrs Dunhill, who is also a fan. And of course she has the chameleon necklace.
