This book is divided into 10 chapters that cover the origin, anatomy, sources, and prices of this precious gem. The first five chapters are devoted to natural pearls, their unique features, origin, history, structure, anatomy, and source. The next two chapters cover cultivation and testing of cultured pearls, as well as their market value. A chapter focuses on the properties of various imitation pearls. The concluding chapters deal with the pricing of pearls, primarily based on an elaborate method using a base price referred to as the “unit base price”. These chapters also consider other pearl uses other than necklaces, such as borders to brooches and festoons. This book will be of great value to pearl traders, manufacturers, and users.
