Lustre of Akoya pearls 


Many experts believe that Akoya pearls have the highest lustre of all cultured pearls, and it has to do with their nacre coating. The Japanese waters in which Akoya pearls grow are considerably cooler -- 10 to 15 degrees cooler -- than those in warmer climates, where other types of saltwater cultured pearls are grown. The cooler conditions cause Akoya pearls to develop their nacre coating more slowly, and with a more compact crystal structure. This is what increases Akoya pearls' reflective and refractive qualities. Even though Akoya pearls' nacre coating is generally thinner than that of most other saltwater varieties -- about a half millimeter thick -- their lustre shines the brightest.
