Hi, welcome hanab, hang in there maybe someone will know. I have a clasp like it; after the 14K there's a circle with an )-( inside. I have no clue what it means.

Mikimoto marker mark is an outline of an Akoya oyster with the letter M inside. Also commonly referred to as the "M" in a clamshell or oystershell

Hanab, Welcome!

That is a popular style of clasp used for some years now but not used by Mikimoto. So doubt the m stands for Mikimoto in this case, more likely the manufacturer of the clasp. I was trying to find out if Milor used that insignia, but no info as yet.
