Diamond Grading Reports
At IDRC we keep a databank of all the reports produced. An IDRC report represents the impartial opinion of unbiased professionals.
All diamonds are unique and individual, created by nature, polished by humans. The IDRC produces quality reports for loose, polished diamonds, describing the unique measurable features of a diamond according to international standards, focused on the “4 C’s” Carat, Colour, Clarity and Cut.
Stones are examined by a minimum of 2 diamond graders. Our experience, combined with modern technology ensure we offer the highest level of expertise in our practice.
