Hi there, awesome research and a great site to help with purchasing! Curious if you have any comments on a stone with these proportions – tends to be outside the “typical” Tolkowski proportions but on a tool like the HCA scores very well. Also just out of the limits of your cut screener.

The HCA offers a false sense of precision based on one man’s unvalidated opinion. It has a known bias for shallow diamonds. I would not put any stock into that measure.
With the bigger table and shallower crown angle, you will have reduced fire compared to GIA EX/AGS 0 Ideal. That’s not to say it can’t look good, but I think it depends on the price you’re being offered and whether or not there are better options available at the same price.
