When combined, those two nucleation innovations are astounding developments. Once again the Chinese have radically altered freshwater culturing, making saltwater and freshwater techniques indistinguishable. They have also introduced a new type of culturing, nucleating with small tissue-nucleated pearls. Some of China's new pearls are all-nacre, some have nacre-coated nuclei, and all are unmarked. After one experimenter used small off-round naturals as nuclei, he sent the resulting freshwater pearls to a gem lab and received a report identifying them as "naturals." If pearl farmers can grow cultured pearls that test as naturals, the market may be in for a wild ride.
Want to know if you've got the real thing? Rub the strand across the front of your upper teeth. It may sound strange, but real pearls will feel rough or gritty while fake ones will feel smooth. This is due to the micropores found on the genuine article.
Imitation pearls are usually made by dipping a glass or plastic bead into a solution of fish scales. The coating is generally fairly thin and will chip over time. Check the pearls for tiny chips or flakes near the hole drilled through them. If you see chips, chances are your pearls are fake.
