With QM’s jewels I think we sometimes forget that she had many people who would have got a few pieces, she had several nieces on her own Cambridge side, the Strelitz princesses must have received something, and the descendants of QV who got married would have got a substantial trinket. It’s also appears quite common that she gave to charities. And don’t forget that Marina, Alice and Mary might not have worn everything they had. We know that QEQM wore very little of the Grenville jewels, maybe she felt the same about QM’s inheritance.
