Witaj społeczność. Pragnę zaznaczyć, że nie znam pereł, więc proszę nie wrzucić pod autobus. Kilka lat temu na skalistej częsci plaży w St Nazaire w zachodniej Francji znalazłem coś, co uważałem za macicą perłową lub częstością muszli. Został celowo złamany przez ciekawskiego członka rodziny i ma warstwową strukturę. Myśli, że po wypolerowaniu i obróbce możnej by do zamienić w cosi pięknego. Z niecierpliwią czek

"Hello community. I want to emphasize that I'm not familiar with pearls, so please don't throw me under the bus. A few years ago, on a rocky part of the beach in St. Nazaire, western France, I found what I thought was mother-of-pearl or a pearl shell. It had been deliberately broken by a curious family member and has a layered structure. He thinks that with polishing and processing, it could be transformed into something beautiful. I eagerly await your feedback."

"Hello community. I would like to point out that I do not know pearls, so please do not throw them under the bus. A few years ago, on a rocky stretch of beach in St Nazaire in western France, I found what I thought was a mother-of-pearl uterus or shell frequency. It was intentionally broken by a curious family member and has a layered structure. He thinks that after polishing and processing, it could be turned into something beautiful. Looking forward to checking"
Identification by species is not possible given the information provided.
These pieces present as molluskan in origin. Likely subclass Heterodonta. While technically they may be considered pearls, concretions might be the better description. Likely formed in the viscera or between a grossly sectioned/infected mantle.
The pieces are high in calcite, low on aragonite and nearly absent of contrasting proteins. Thus no gemological value other than folk art. Pearls of any type cannot be polished to improve luster and appearance.
For someone like me, these types interesting nonetheless. Often abberations of pearls have some scientific value, but without an anatomical context on the whole (in situ) there is not much more I can add.
It's quite alright to ask for help! We encourage questions greatly among this group. Thank you for sharing these images with us.
