Can anyone identify these please

I am interested in some more information on this pearl necklace I inherited from my Japanese mother in law. They were in a Mikimoto box but do not have that stamp. From the appraisal I received:-
The Akoya cultured pearl necklace consists of 101 pearls graduating in size from 7.3mm to 3.3mm. The necklace is strung without knots on a sterling silver clasp with a single 3x3.5mm cultured pearl and measures approximately 18" in length.

Color: White with a slight pink undertone
Color matching: Excellent
Roundness: Excellent
Nacre thickness: Excellent
Nacre evenness: No bumps, spots or blemishes
Overall quality of necklace (scale 1 to 10): 9.5
Comments: Excellent necklace with top quality pearls.

It is not possible to get more information than that
It is a nice little postwar japanese akoya pearl necklace. It needs maintenance. If you plan to wear it, please consider washing and restringing it. With knots between each pearl (which I personally prefer, no matter how big or little the pearl is), it will get longer.
Clasp is really beautiful, and it can also be polished.
Best thing is that all of that you can do by yourself.
Regards

Thank you. Any tips on how to polish the clasp without damaging anything? I will be selling this but at the moment am not having much luck with that. Maybe a shiny clasp will help

Most efficient way, and a lot of old jewellery passed through my hand, is short and gently washing it with toothpaste and with very soft toothbrush, avoiding pearl. After that wiping it with the silk cloth should do the job.
Of course, you cannot expect it will be just as new but it will be much better. After all, a little patina gives it a charm.

I don't think a shiny clasp will make a difference; people are buying the pearls. When they have the strand restrung with knots, they can clean the clasp before reattaching it. Or, they may swap out the clasp entirely. I found your listing on the auction site, and I suggest you make it clear that it is not a Mikimoto necklace, just a Mikimoto box. People may be slow to bid because it looks like this is your first listing and you don't have any feedback.
