Holloway Cut Adviser

The Holloway Cut Adviser (patent pending) evaluates the visual appearance of a round diamond as a combination of four factors - Light Return, 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.

In order to use the system you must know Total Depth %, Table % and Crown and Pavilion angles or %.

We recommend you use the Holloway Cut Adviser as a final check on your selection.
