me TOO on Holloway Cut Adviser

No I don''t have a picture. But I get waaay different results running the percentages on a stone.

Depth 60.7%
Table 58%
Crown 13.4%
Pavilion 43.7%
Crown Angle 32.5°
Pavilion Angle 41.3°

If I go with the Angle I get a visual performance of 2.4

If I go with the % I get a visual performance of 1.7.

How can there be so much difference? I have someone that owns the stone and it matches a stone that scores in the 1.7 range GIA.

Rounding off error. Use the angles, it is the more accurate number.

This is normal, angles are more accurate so use those if available rather than percentages.
