Is it really Kojima? What are these pearls?

[MintyFresh]

I purchased this brooch from EBay for $75. Seller listed it as Kojima but there’s no receipt or identifying marks. However, it was so pretty, I took a chance. Does anyone know what kind of pearls these might be? The brooch measures about 2 inches wide. Perhaps the seller is even a member?

One of the long outer pearls is just a bit loose. Can I glue it myself or should I take it to a jeweler?

They are freshwater pearls. I have two brooches purchased from Kojima. I can’t remember off the top of my head, but maybe somewhere around 2013. They were handmade by a woman in Hong Kong. I mostly wear the large one as a pendant, and the smaller one on a wristband. Here are some old photos that I’ve posted before-

Hello and thanks for asking about these.. I feel like I should probably chime in on this one.
These brooches are/were made by the sweetest lady in ALL OF HONG KONG (Sorry Terry and Ann). As a family we have been buying pearls from her and her husband (and now their two AMAZING daughters) for decades.
It was explained to me many many years ago that when she was quite young she worked as an embroiderer in China, with a specialty in highly detailed roses.. when she found herself in Hong Kong many years later with pearls all around her.. these fantastically creative brooches were a cake walk in comparison to the fine fine needle work. Always innovating on her designs, I bought and sold these for years and years. I am surely NOT the only person who visited this pearl dealing family in HK and thought these brooches were fantastic... so I can not say if these came through Kojima or not.. but I CAN SAY that the maker is a true treasure and I never leave her booth empty handed.
