Real Mikimoto South Sea pendant?

[Karamel]

Hi everyone,

I found this vintage/used Mikimoto South Sea Pearl Pendant and would like to learn everyone’s opinion on its authenticity. The seller listed it as a 13mm South Sea pearl set in 18k white gold that they got from a second hand shop in Japan. The pendant came with the Mikimoto box and has the “M” marking, as well as “K18WG” stamp and “0.12” for the diamonds. When I tried to reverse image search the pendant on Google, I couldn’t find any similar product from Mikimoto at all. I’m also wondering if it’s a real South Sea pearl. Please let me know what you think and thank you so much for your help!

I don't see any reason to doubt that it is what it purports to be.

Let's see what others who are more familiar with Mikimoto think.

thank you! It is under $1k, that’s why I’m a bit unsure. The seller just sent me this clearer picture of the stamped M.
