Firstly I’m always with older picture identifications it’s all angles, angles, angles. One millimetre off and you’re working on theories due to shapes and refractions etc.

Secondly it’s the double edge sword of why we love QM so much is that her jewellery collection was so large we’re still digging up artefacts from it. If it was smaller identification then from whose got what would be a tad easier.

However I think Beth is bang on the money here, I can see pearls, refractions are very misleading to stone size and gaps and the fact is PA is a direct descendant. This isn’t a major or important piece that would have been left by QM to the Queen but very much that type that would have passed down to her other children/daughter in laws.
