Objective

You will learn the history of diamond and why diamond is so valuable. The development of cutting of diamond, how diamond reflect light. Using a loupe, you will learn how to grade a faceted diamond based on 4Cs i.e. clarity, colour, cut and carat weight. Loupe, lighting and diamond samples will be available during practical sessions. . How diamonds are priced in relation to Rapaport report and the different types of diamond quality reports available in the market.

Objective

Advanced technique in grading of clarity, colour and cut of a diamond.  For example, observe the quality of cut in detail where you will be taught how to observe the hearts and arrows.  Grading of mounted diamond and also how to identify natural diamond from imitations like cubic zirconia, synthetic moissanite, and synthetic diamond.  Compare the usefulness of various instruments like Jemeter digital 90, Presidium Reflective meter, Presidium Tester in testing natural diamond from some of imitations.  You will also view some of the latest treated diamond like irradiated diamond, High Pressure and High Temperature (HPHT) diamond, laser drilled diamond and fracture filling in diamond.
Outline
  1. Clarity, colour and cut grading in detail.
  2. Look at the cut grade in more detail like how to estimate    the table percentage, crown angle, girdle thickness, quality of polish and symmetry.
  3. Examine natural diamond from synthetic moissanite, cubic zirconia, synthetic diamond.
  4. Examine treated diamond like irradiated diamond, High Pressure and High Temperature (HPHT) diamond, laser drilled diamond and fracture filling diamond.
  5. Learn about international disclosure rules.
  6. Practical sessions.
