At the completion of each program the student is granted the internationally recognized diamond certificates from

AMERICAN INSTITUTE OF DIAMOND CUTTING, INC.

The tuition cost includes all practice diamonds and equipment while attending the Institue, there are no hidden or additional cost to the student. The three programs when combined offers the student a firm foundation in self-employment. The programs covers round brilliants, fancy cutting, sawing, bruting, recutting, and repairing. The programs also include finished diamond grading and rough diamond grading. All instruction is individualized. A catalog is available on the diamond cutting programs, application is included. Please note all information in the catalog is outlined on this website.

The art of Diamond Cutting, once acquired, allows the student to become employed at almost any level in the Jewelry and Diamond industry.

The following are some of the job positions that would be available:

  • Sales consultant (jewelry and diamond stores).
  • Managers for retail (jewelry and diamond stores).
  • Diamond buyers for retail outlets.
  • Diamond buyers for wholesale outlets.
  • Travel consultant for major diamond firms.
  • Diamond consultant for private companies.
  • Diamond factory supervisor.

9. How to make all mains on crown into a perfect square of 90 degrees, by eye evaluation, and make the in-between facets (bezels).

10. How to cut the pavilion mains and its in-between facets on angle and how to match them to the top crown mains.

11. Knowledge of the critical angle for both crown and pavilion and variation of table size for maximum brilliance.

12. How to make a culet.

13. How to brillianteer a diamond, i.e. putting the 40 remaining facets on both crown and pavilion.

14. How to calculate the finished weight of a cut diamond to within a few points from the rough before even attempting to cut.

15. How to judge and what to look for in determining a fine made round brilliant diamond.

16. Techniques on maintenance and balancing of all cutting equipment to ensure top performance for a high standard of work.

17. Methods used to prepare and charge a diamond wheel and how to maintain optimum cutting and polishing surfaces.

18. How to mount and set diamonds in various pots.

C. PROGRAM COMPLETION STANDARDS

  1. Each student will be assigned specific tasks for completion without supervision or assistance and a final passing evaluation grade will be given.
  2. The student must demonstrate that they are able to cut a round brilliant from a sawed and bruted state to the finished product.
  3. The student must demonstrate that they are capable of doing minor repairs to a broken (4 point) diamond with satisfactory results.

A certificate will be awarded to those students who successfully complete the prescribed program.
