Chinese Freshwater Pearls Go High-Tech: Eric Yen in JCK

In “China’s High-Tech Pearls Have Arrived, But Most U.S. Buyers Haven’t Noticed,” JCK looks at how China’s freshwater pearl industry has quietly reinvented itself. Eric Yen is the trade voice in the story, and the article is illustrated with pearls from our inventory, including the Amethyst Purple Edison strands shown here.

Not the pearls you remember. Many American jewelers still picture Chinese freshwater pearls as off-round, creamy goods sold by the kilo at trade shows. Eric’s advice to JCK is to erase that picture. By his estimate, about 90% of the trade has not seen the new production yet.

The research behind the story. JCK’s reporting draws on a new study in GIA’s Gems & Gemology journal (Summer 2026), “Policy-Driven Sustainability in China’s Freshwater Pearl Culturing Industry,” by five researchers from China University of Geosciences in Wuhan. It traces the industry since 1949 through four stages: early exploration, rapid expansion, regulation and today’s sustainable development. Output peaked at 5,265 tonnes in 2006, when crowded, over-fertilized farms polluted lakes and pushed prices down, a pattern the authors call a “volume-driven growth trap.” Strict environmental rules then cut production to 454 tonnes in 2020, just 9% of the peak. The industry has since rebuilt around cleaner methods, including fish-and-mussel polyculture, smart pond systems and selective mussel breeding, and output recovered to 1,125 tonnes in 2024. The authors also note that a single pearl mussel can filter more than 100 liters of water a day, so well-managed farms can help clean the water they use.

High-tech farms. Today’s farms use sensor-monitored ponds, nutrient feeding systems and closed greenhouses that, according to JCK, can grow 9–13 mm Edison-type pearls in about a year and a half instead of three to five years. Eric saw the technology firsthand on our 2025 study trip to the Shanxiahu pearl hub in Zhejiang: underwater chips tracking pH and water temperature, feeding tubes, and AI grading and drilling systems. He describes it as part of a green initiative to keep the water clean, backed by serious government investment.

Purple is the new standard. A mussel-breeding program now produces purple pearls at a reported rate of about 97%. Eric tells JCK that traditional pastels like light pink, peach and orange are the old look, while intense purples, metallic overtones, bronze and copper are what’s new. We have carried these colors since before 2020, yet to most retailers and consumers they are still very new.

Getting the names right. The article also covers the naming debate. “Freshwater akoya” is a misnomer: true akoya pearls grow only in saltwater oysters, and saltwater pearls are worth considerably more, so the difference has to be disclosed. Eric raised this in 2024, and our buyer’s guide to the term “Chinese akoya” explains it in detail (linked below).

Since 2024, more supply and softer demand have kept commercial goods flat or falling, Eric says, while truly fine material, such as very round, closely matched 13–15 mm Edison strands in intense colors, remains hard to find.

Show them like fine jewelry. Eric believes the knowledge gap comes down to presentation: many stores don’t put freshwater pearls in their jewelry cases at all. At Tucson and JCK Las Vegas, we show quality Edison pearls in a lit fine jewelry showcase, the way pearls at this level deserve to be seen. JCK also pictured our 15–18 mm purple strand and a 13–14 mm metallic strand like the one below.

See them in person. We carry fine Edison strands in amethyst purple and metallic bronze and copper. Retailers and designers can apply for a trade account below to see wholesale pricing, or meet us at an upcoming show.
