EDUCATION

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.

POLISHED DIAMONDS

Once a rough diamond has been fully examined, the stone is marked to decide how it should be cut to yield the greatest value. Due to the diamond’s atomic structure, it can be cleaved in four directions parallel to the octahedron crystal faces. This process is what produces the beautiful facets you find in diamonds which make them sparkle. Only then, they are sent to be certificated and graded using the industry standard 4 C’s criteria.
