The irregular baroque shape is common. Moreover, it takes 5-6 years to reach a size of 7-9mm. A 10mm pearl, which takes about 8 years to grow, is a rare masterpiece, with only one in 10,000. ◆ It is characterized by being made entirely of nacre, without using a shell nucleus. Most cultured pearls use a "shell nucleus" in the center to create the nacre layer. In the case of an 8mm pearl, the size of the shell nucleus is about 7.5mm, so there is only a small amount of nacre. Freshwater pearls are cultured without using this "shell nucleus," so each pearl is made entirely of nacre. ◆ The beauty of pearls is special. The smooth luster like silk and the iridescent light dancing on the surface tell the story.
