Sources and artifacts, famous gems, buying tips and much more are included in this lavishly illustrated book. While objects of desire are found throughout the natural world, physical beauty is too often ephemeral.
From the allure of a man, woman, flower or butterfly, through the fleeting moments of a sunset, there is little that lasts and practically nothing that can be passed down to our descendants.
The exception is precious stones. Not only are they the most durable creations of mother nature, but their visual splendor is truly eternal. The product of nearly 40 years of firsthand experience, it covers every aspect of the subject from A-Z.
History, sources, prices, quality analysis, synthetics and treatments, everything is here. With over photos, maps and illustrations and references, it is nothing less than a tour-de-force of gemological scholarship.
Inclusions & Exclusions
Hughes Statement The first half of the book defines external and internal inclusions, describing each variety with numerous full color examples. What makes this work outstanding is the section in which inclusions are tracked from the rough to the cut and how the integrity of the diamond can be compromised by depth and position of the remaining inclusions.
Additionally, an entire section is devoted to the diamond manufacturing process and its relationship to inclusions. In this area inclusions are examined with regards to heat, pressure, rotation, and other mechanical influences.
Inclusions trapped in diamonds are full of information that in many cases is still to be scientifically interpreted.
