A pearl found in an oyster can be worth anywhere from nothing to millions of dollars, depending heavily on whether it's a common cultured pearl (often low value, $50-$2000+) or an extremely rare natural pearl (potentially $1,000s to $2M+), with factors like size, luster, shape, and type (Akoya, South Sea, Tahitian, Freshwater) determining its price. Most restaurant finds are small, lower-quality cultured pearls with sentimental value, while truly valuable natural pearls are exceptionally rare finds, often auctioned.
The value of a pearl can vary dramatically depending on many factors, such as pearl type, size, color, surface quality, and more. A wild pearl will be worth more than a cultured pearl. So, how much are pearls worth? To keep it short, on average, a pearl's value ranges from $300 to $1500.

The pearl, found off the coast of Palawan Island in the Philippines, was later valued at around $100 million, making it one of the largest natural pearls ever discovered.

Pearls are made by marine oysters and freshwater mussels as a natural defence against an irritant such as a parasite entering their shell or damage to their fragile body. The oyster or mussel slowly secretes layers of aragonite and conchiolin, materials that also make up its shell.
Harvesting cultured pearls often kills the oyster, as many farms kill the animals after the first harvest for their meat and shell, though some try to recycle them for multiple harvests, while wild pearl harvesting kills thousands of oysters for just a few pearls. While some techniques allow oysters to survive and produce more pearls, especially with skilled intervention, the overall industry often involves stress, harm, and eventual death for most mollusks.

The most expensive pearl colors are often deep, rich hues like Golden South Sea (especially 24k deep gold), rare Peacock Tahitian (dark green/blue/purple overtones), and intensely pink or pink-overtoned White South Sea pearls, with value heavily depending on rarity, luster, size, and lack of blemishes, rather than just the base color itself. While white and black are common, specific, saturated, and rare overtones within these categories command the highest prices.
A Filipino fisherman unknowingly slept for years beside what would later be revealed as the world's largest natural pearl—a massive 34-kilogram gem valued at nearly $100 million.

It was Jackie Kennedy who said 'pearls are always appropriate,' meaning that they suit all occasions and all outfits. Indeed pearls are still worn by many brides on their wedding days and feature in most jewellers' windows today.
The sad reality is that old, second-hand cultured pearls aren't worth a lot. There's no obvious place to sell them and you won't get much from a jeweller or by putting them on eBay. Our advice is to keep them as a memento or give them to someone who'll appreciate them.
