The Edison Pearl is named after Thomas Edison. Thomas Edison had more than 2,000 inventions, but there were two things he could not create in his lab - pearls and diamonds. In order to “make up” for Edison’s regret, the high-tech development of the Eco-cultured pearl is named the Edison Pearl, also in honor of Edison.
The Edison pearl is a fresh water cultured pearl with nuclear nucleus. In general, freshwater pearls are produced by seedless culture, which generally takes 3-5 years to grow. The finished freshwater pearls have different shapes, relatively few are perfectly round, and the size is about 5-9mm. The Edison pearl, on the other hand, mimics the way seawater pearls are raised by implanting a nuclear mold in the mother. Edison pearl takes 3-5 years to grow, which is longer than the three to five years required for a typical freshwater pearl. Therefore, the size of Edison's pearls is twice that of ordinary freshwater pearls (9-16 mm in diameter), with a high rate of roundness and excellent luster.
