1. What are the percentage of stones that scores triple very high on the Bscope

If you mean to ask what percentage of *all* stones truly score tripe very high on the Brilliancescope ... consider this.  It is reported that less than 1% of all diamonds cut on the market meet the standards for what strict, conservative graders would consider true Hearts & Arrows diamonds.  Among that small niche of true H&A's an even smaller percentage of those score triple very highs on the BrillianceScope.  Among 99.9% of the factories that cut true H&A's a very very small percentage of those actually get triple very highs on the BrillianceScope.  The practical benefits of BrillianceScope testing reflects how the diamond will appear in direct or strong light conditions. The question has been raised as to what the BrillianceScope is actually measuring.  A safe and simple answer to that question is "total overall brilliance in direct light conditions".  People come to our store every day to draw these comparisons with their own 2 eyes.  Today we had the opportunity of helping a gentleman for whom we called in 3 Lucere diamonds.  Before I even showed him the BrillianceScope results on any of them I let him see all of them with his own 2 eyes in the appropriate light conditions and he, very easily picked out the most superior stone.  It was no surprise that *that* particular stone was the one with the best BrillianceScope results.

2.  Does all of these triple very high score always do well with the ISEE2 machine and vice versa?

Absolutely NOT.  As magnum properly pointed out this is a completely different optical analysis. I have had the opportunity to test and analyze many diamonds (H&A & non) that do outstanding on the Brillancescope and not so good on the Isee2 and vice versa.  Some of this is discussed and demonstrated in our tutorial on the subject.  It is the rarest of H&A cuts that get the highest results on both technologies.  A characteristic that will be part of what will constitute our signature line once we get that rolling.

Hope that helps.

it is always harder to find a "mind clean" stone than a eye clean stone.
