New Book- Diamond Inclusions

The industry first book devoted entirely to diamond inclusions, Diamond Inclusions by Nizam Peters

New Book DIAMOND INCLUSIONS

will be available January 28th 2011

 PLEASE GO TO OUT OFFICIAL DIAMOND INCLUSIONS BOOK WEBSITE:

Diamond 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.

An internationally recognized school dedicated to teaching the art of diamond cutting and rough diamond grading.


 TABLE OF CONTENTS

 

EXTERNAL FEATURES

 

External features can be divided into four general groups in which they occur in many different varieties and form.

 

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 seven)

    4. Features that are both external and internal (Chapter eight)

 

CHAPTER ONE

Naturals, growth markings and radiation stains.

 

CHAPTER TWO

External grainings, twinning lines and knots.

 

CHAPTER THREE

Cavity, pits and nicks.

 

CHAPTER FOUR

Surface hairline feathers, cleavage and fracture

breaks close to the surface.

 

CHAPTER FIVE

Scratches, wheel marks, cutting lines (polishing lines)

and extra facets.

 

CHAPTER SIX

Bearded girdle, rough girdle and abrasions.

 

CHAPTER SEVEN

Burnt facets, burn marks, slight percussion marks or

bruises.

 

CHAPTER EIGHT

Cleavage and fracture breaks on the surface.

 

INTERNAL FEATURES

Internal features can occur in many different varieties and

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 and excessive

wear and tear (Chapter thirteen)

 

CHAPTER NINE

Included crystals, internal knots, twinning lines,

internal graining and swirl lines.

 

CHAPTER TEN

Carbon inclusions, pinpoints inclusions, carbon

pinpoints and clouds.

 

CHAPTER ELEVEN

Fracture and cleavage feathers, internal hairline

feathers and colored feather inclusions.

 

CHAPTER TWELVE

Color banding, color zoning, stress and strain.

 

CHAPTER THIRTEEN

Bearded girdle (feathered girdle), rough girdle,

excessive percussion marks or bruises.

 

CHAPTER FOURTEEN
