Many thanks Franck. Great information. So now we know for certain from Vincent Meylan's work that Mrs Greville did own very expensive pearl earrings. Pearls of over 100 grains each are very rare, and the price she paid for them was astronomical. What would we all do without Vincent Meylan's scholarship? Thank you Vincent!!

Another factor which makes me think that the earrings worn by the Duchess of Cornwall are Mrs Greville's is that the stud section has a triangular shaped diamond. It is an unusual choice; something which I associate with Mrs Greville.



The other thing which struck me about these pearls is that the colour makes me think they are South Seas pearls. The characteristic silvery whiteness is strikingly clear against the creamy pearls in the Duchess' choker.
