Round Brilliant diamonds:
The Search by Cut Quality for utilizes the Holloway Cut Ranking (U.S. Patent 7,251,619) for automatic evaluation
of the visual appearance of a round diamond as a combination of four factors -
Brilliance, Fire, Scintillation and
Spread.
The grading scale is: 0-2 Excellent, 2-4 Very Good, 4-6 Good, 6-8 Fair, and 8-10 Poor. A score of zero is almost impossible because many of the factors conflict.
Only diamonds with known Table,
Crown, Pavilion,
Culet and Girdle are
included into this search. Please read the advanced part of the tutorial on how these
factors affect the visual appearance of the diamonds.
For stones, you've found elsewhere, we recommend you use the Holloway Cut Adviser as a final check on your selection.
