Frequently Asked Questions
What is the difference between white and coloured diamonds?
White (colourless) diamonds are graded on the D–Z color scale. D is completely
colourless and the most valuable. This course focuses on the D–H range which is the most
commercially important range traded in Surat's diamond market.
How is this course different from the 610-hour course?
This 410-hour course focuses specifically on white diamond valuation without the
Rapaport system and market trading modules. The 610-hour course covers the complete business
curriculum including Rapaport, LB/LC shading and buying/selling theory. We recommend the
610-hour course for those wanting to run a full diamond business.
