f. Lighting conditions and materials used for rough color identification.
g. Examining rough crystals for inclusions under the microscope.
h. How and where to open windows on rough diamonds.
i. Identifying and judging the depth of cleavage feathers, fracture feathers, carbon and pinpoints.
a. First initial lecture on classification of rough gem diamonds.
b. Classifying parcels of rough diamonds for color.
c. interpreting color according to the surface texture on the rough.
d. examining rough diamonds and plotting their inclusions with only a 10x loupe.
e. Judging inclusions and their depth for possible removal during manufacturing.
f. Orienting a rough diamond for placement of the table facet.
g. Understanding pricing and how it is used for rough diamonds.
h. Pricing individual single large crystals and parcels of small rough.
i. Identifying knotted (natted) diamond crystals.
j. The application of lasering rough diamonds and when does it apply. (practical examples are shown)
The rough diamond grading program at A.I.D.C. Inc. is the most comprehensive of its kind and the only program that is equipped with its own text books on rough diamonds. Both books come in hard covers with full color plates displaying individual diamond crystals and parcels of rough with detail explanations on color and inclusions within the rough diamond
The titles are, "Rough Diamonds, A Practical Guide" and "Rough Diamonds, Internal and External Features." Author-Nizam Peters. These books can be purchased separately.
(See also other book titles)
a. How to select rough diamonds for fancy shapes.
b. Expected weight recovery for fancy shapes.
c. Proportional analysis of rough diamonds for fancy shapes.
d. Second lecture on classification of both gem and industrial rough diamonds.
e. Pricing of industrial diamonds and their possible market share.
f. How to classify and price mine run parcels.
g. How to use the diamond sieves.
h. Understanding the difference between borderline industrials and gem quality rough.
i. What is meant and how to interpret near gem rough.
j. Fluorescence and its effect on rough diamonds.
Practical examples of rough diamond crystals and parcels of rough are examined by students in all areas of the rough diamond grading program.
a. Fancy color as it relates to rough diamond crystals.
b. Fancy color banding, zoning and centers within rough diamond crystals.
c. Proportion and symmetry analysis and its affects on fancy colors.
d. Individual analysis of rough crystals for shape and weight retention.
e. Individual rough analysis for color, clarity and price.
f. Case examples on calculating the outcome for extra large individual rough diamonds.
g. Identifying and checking for fake rough diamond crystals.
h. Case history on what to expect on switching and slight of hand for rough diamonds.
i. Actual rough diamond purchases in the field and what to expect.
j. Funds transfer, payments, transportation and exportation of rough diamonds.
k. Import and export laws in different countries.
Several hundred carats of rough diamonds, originating from both Africa and South America are kept by the institute specifically for teaching, grading, and sorting. Two hundred and twenty carats of these diamonds were selected over a two year period by the Director during mining operations in South America. The rough crystals are a cross section of varying shapes, sizes, color, and clarity, thereby giving the students invaluable insight to rough diamonds they would normally encounter in the field.
The director of the Institute personally teaches the rough diamond grading program. He is also the author and photographer of the book, "Rough Diamonds, A Practical Guide". For further information on Mr. Peters, please see founder and faculty information.
A certificate of completion is issued to the student at the end of the rough diamond grading program.
Assistance and Field Support
Upon completion of the rough diamond grading program, the Institute offers a unique package to support the students while in the field. The institute will make available the services of the cutting and polishing department and extend technical help in marketing both the rough and polished diamonds. These and many other services are available to assist the student during field operations.
To enroll in the program an application is required to be filled out and submitted with two passport size photographs and a fee of $150.00 which is part of the total tuition cost. International students are not required to have a visa for the rough diamond grading program. They can apply for a tourist,business, or visitors visa. All funds must be paid in U.S. dollars in the form of a certified check, money order, cashiers check or wire transfer.
