clay Rough Rock Total Posts: 7 Last Post: 1/28/2002 Member Since: 1/21/2002	What is a better determiner of brilliance and cut quality - a true hearts and arrows pattern or a low holloway score? Will a great Holloway score decrease the chances of light leakage? I am looking at two diamonds to purchase over the internet. One is a hearts and arrows (F color) with a holloway score of .9 and one is an AGS000 ideal cut (D color, non H&A) with a Holloway score of .3! Which one will look more brilliant?

However, 0.9 or 0.3 are both great scores and as you can read on the HCA page (after evaluation is done) you don't have to split hairs for HCA < 2 Pricescope

It is possible for light to leak from H&A's diamonds as you can see from the Idealscope image (the second image is not an arrows view - an arrows view does not effectively show leakage the way the ideal-scope does.
