I usually ignore the claims made about jewels, but the Greville bequest is a bit different. Hugh Roberts says there’s were over sixty items and shows the box it came in. What would a small item of jewellery be that Mrs Grenville would still have worn, pearl earrings, seed pearl necklace, and also why wouldn’t QEQM have chosen not to wear it. Realistically I think it reasonable to assume that we have seen most of the bigger items. Perhaps a few yet to be unearthed but Iwonder what the rest are. Maybe they were too Art Deco for the QM. My guess is that any information will not come from Buckingham Palace but from the Boucheron and Cartier archives. It is also possible that we have seen a lot more than we think we have but have assumed a different source.
