About sorting and valuation rough diamonds.
In nature there are no perfect crystals, or two identical diamonds, so their grading involves sorting them by more than 8,000 criteria. Each crystal is described in accordance with 4 grading characteristics: weight (size), shape, defects (quality), and color.
