Great question, and I see you’ve fallen into the same confusion as quite a few people after a trip to Asia—especially in Bangkok, where the markets are full of jewelry labeled "cultured pearls." I also brought back a cultured pearl necklace from there a few years ago, and I did some digging afterward because, like you, I was hearing all sorts of contradictory things.
Yes, pearl farms do exist in Thailand, particularly around Phuket and in the southern part of the country. They mostly produce freshwater pearls. It’s a real industry, even if Thailand isn’t the world’s biggest producer. In Asia, the leaders are still China (for freshwater pearls), Japan, and the Philippines (for Akoya and South Sea pearls).
The term "freshwater" literally means "eau douce"—these pearls come from mussels cultivated in lakes, rivers, or artificial ponds, unlike saltwater pearls, which are produced by oysters living in the sea. Freshwater pearls are generally more affordable, a bit less uniform in shape, but nowadays, some are truly stunning in quality. They’re often used for necklaces sold in Thailand because they allow for beautiful jewelry at more accessible prices.
What often confuses people is the term "cultured pearl," which can be misunderstood. A cultured pearl, whether freshwater or saltwater, is a real pearl—but it’s created with human intervention: a nucleus (or a piece of tissue for freshwater pearls) is inserted into the mollusk, which then produces nacre around it.
If your necklace is labeled "freshwater cultured pearls," it’s very likely from a farm, and that’s not an issue—so long as it’s well-made, the pearls are shiny, and there aren’t too many imperfections, it’s a fantastic souvenir.
You could also do a quick home test: rub two pearls together. If they catch a little, like "grains of sand," they’re real pearls. If it’s too smooth, watch out for plastic or glass imitations.
Anyway, keep your necklace safe—it’s probably a real
cultured pearl necklace
, and a lovely nod to your time in BKK! 😊
