Cut Quality Search tool..

[lauralu]

Would these numbers from the cut quality search tool pretty much guarantee a really beautiful stone? Would any stone that comes up in the search tool scoring 1 or less in the HCA category going to be winners?

My understanding of the HCA is that as long as below a 2 should be a good performer assuming symetrical diamond and a very good polish.

Lurker here for abour a month. Looking for a e-ring too 2 years down the road... so shopping around too.

No. Actually, no stone scoring 2 or less is automatically a winner. Gary specifically states it''s not to be used to pick a stone. Once you get a desirable score, it''s time to move on to more info, such as Sarin, IS pics, etc.

Stones I''ve seen with scores less than 1 usually have somewhat shallower numbers, which can have head obstruction/contrast scintillation issus. But that''s not a given. Again, each stone has to be evaluated on an individual basis.

The stone you have scored could very well be a beautiful stone, but more info is needed to say for sure.

It is a great guide to get you started...it should weed out truly non performers to begin with?

In the end I am thinking you must rely heavily on the online venders and what their eyes see for you after finding out everything else looks like a go....

thank you for your reply''s....

Basically stones scoring 2 or below are then considered to be worth further evaluation with Idealscope, trusted vendor input etc. It is an elimination tool, so usually diamonds scoring over 2 are considered to be lesser performers - however in some cases stone which do score over 2 with top symmetry can still be worth considering ( to muddy the waters a bit!) But if you have a diamond with Idealscope images and other cut quality aids, and vendor input then the use of the HCA is limited.

This page should help also - http://diamonds.pricescope.com/ideal.asp
