Book – DIAMOND INCLUSIONS

PLEASE GO TO OUT OFFICIAL DIAMOND INCLUSIONS BOOK WEBSITE:
Inclusions is the first book ever published that is devoted entirely to
inclusions; their size, position, quantity, type, color and how they affect the
finished diamond. It covers not only external and internal characteristics but
documents and tracks diamond inclusions from the rough crystal to the fully
faceted gem product. Five rough gem diamonds ranging in size from 4.72cts to
17.58cts are documented in this manner. Additionally, diamond inclusions are
further examined in a separate section on how they are affected during the
sawing, bruting and polishing processes. It discusses how heat, pressure,
friction, diamond powder and other mechanical areas that may affect certain
types of diamond inclusions.

author Mr. Nizam Peters has spent over four years primarily photographing and
documenting the varieties of diamond inclusions in this current work. He is the
current author of several other books and the director of the American
Institute of Diamond Cutting, Inc. An internationally recognized school dedicated
to teaching the art of diamond cutting and rough diamond grading.
TABLE OF CONTENTS
External features can be divided into four
general groups in which they occur in many different varieties and
1. Features that are primarily natural in origin
(Chapters one thru four)
2. Features resulting from the manufacturing process
(Chapter five and six)
3. Features resulting from wear and tear (Chapter
4. Features that are both external and internal
Naturals, growth markings
and radiation stains.
External grainings, twinning
lines and knots.
Cavity, pits and nicks.
Surface hairline feathers,
cleavage and fracture
breaks close to the surface.
Scratches, wheel marks,
cutting lines (polishing lines)
and extra facets.
Bearded girdle, rough girdle
Burnt facets, burn marks,
slight percussion marks or
Cleavage and fracture breaks
on the surface.
Internal features can occur in many different
shapes. They can be classified into four general categories.
1. Features resulting from mineral type inclusions
(crystalline and solid) imbedded in the body of the
diamond (Chapter nine)
2. Features resulting from impurities that existed
within and around
the formation of the crystal (Chapter 10)
3. Features resulting from structural defects during
and after the
process of crystallization (Chapter eleven and twelve)
4. Features resulting from the manufacturing process
wear and tear (Chapter thirteen)
Included crystals, internal
knots, twinning lines,
internal graining and swirl
