Pearls are very alluring and hold a quality that both defines elegance and natural beauty. There are more varieties and availability of pearls today than ever before. The cultured pearl? now rivals with fine diamonds, sapphires, emeralds, and rubies. Today most pearls are cultured, meaning that the mollusk is purposely inserted with an irritant or nucleus?from which it creates a pearl. A better way to think of the difference between natural pearls and cultured pearls is to think of the natural pearl as a result of the mollusk working alone and the cultured pearls as a product of nature being helped by science. Cultured pearls are not fake?like many people may think. The culturing process takes from two to three years and is a very delicate process. The pearl farmers have little control on what the outcome of the pearl will look like or if the mollusk will reject the nucleus. Not all pearls are fine quality or even desirable at all. The end result is ultimately a consequence of nature. Choosing pearls that are of the best quality are determined by luster, nacre thickness and quality (the outer layer), color, surface perfection, shape, and size. The biggest factor of pearl quality is nacre thickness and quality which determines how long the pearl will last. Nacre thickness determines the longevity of the pearl and nacre quality determines how light reflects through the layers of the pearls. High [1] [2] [3] [4] 下一页 |
