Pearl necklace

Pearl necklace. Pearls are accretions of nacre (calcium carbonate) secreted by certain oysters and mussels. The presence of a foreign body (such as a parasite or a grain of sand) within the shell triggers the secretion of nacre by the molluscs mantle. Thin layers are deposited on the irritant particle and, over several years, a pearl is formed. Although commercially valuable pearls are obtained from freshwater mussels and oysters, precious pearls can come from ocean oysters. Cultured pearls are cultivated by inserting fragments of clam shell into the shells of farmed mussels and oysters

Jewellery Polished Precious String Pearl Necklace

EDITORS COMMENTS
This print showcases the timeless elegance of a pearl necklace. Pearls, known as accretions of nacre, are formed when certain oysters and mussels secrete calcium carbonate in response to the presence of foreign bodies within their shells. Whether it be a tiny parasite or a grain of sand, these irritants trigger the molluscs' mantle to deposit thin layers of nacre on them over several years, eventually resulting in the creation of a precious pearl. While commercially valuable pearls are typically obtained from freshwater mussels and oysters, this photograph reminds us that ocean oysters can also produce exquisite gems. The string of multiple polished pearls featured here exemplifies nature's ability to transform an irritant into something truly remarkable. It is important to note that cultured pearls have been cultivated through human intervention. By inserting fragments of clam shell into farmed mussels and oysters, individuals have played a role in encouraging the formation of these stunning jewels. Science Photo Library has beautifully captured this piece of jewellery, emphasizing its allure without mentioning any commercial use associated with it. This image serves as a testament to both nature's artistry and humanity's appreciation for beauty found within our oceans.
