Just updated my post with some more information and found another necklace on the net with the MP stamp but with a guarantee card. So hopefully our pearls are Mikimoto.
Thanks, I understand. It's all down to personal choice I suppose. Only an auction would establish a factual price. It's what people are prepared to pay. I would be happy to know they are genuine Mikimoto and understand why the mark on the clasp is not an M but MP.
Thank you B. I have contacted Mikimoto UK but they seem reluctant to reply. Except when I asked for a quote to have them re-strung, when they got back to me immediately.🤪
My wife has just inherited some Mikimoto pearls from her mother, originally purchased by her Grandfather for her mother just after WW2
We think in 1947 but the last letter in the Birmingham Hallmark is hard to read. But not 1947. 9kt Gold clasp.
The clasp has a very small mark with the letters...
