520 |a Gemmological Instruments deals with the developments in diamond grading equipment and gem testing instruments since the publication of the first edition in 1978. These developments include improvements in the versatility and styling of existing instruments such as the reflectivity meter, the composite spectroscope, and the refractometer. It also addresses the criticisms in the first edition and provides a discussion of the advantages and disadvantages of different gem testing equipment. This book is organized into 16 chapters that describe groundbreaking instruments like the thermal conductiv.
