I just plugged all the data regarding a supposedly very good rock – 1 caret ACA, H&A costing almost $8500 into the Holloway Cut Adviser and it came back with a 2.4 rating. Which is only “very good”. I put in data from a couple regular Ideal cut diamonds costing almost $3000 less and they came back rating 0.9 and 1.5 which is “excellent’. What am I missing? And yes I double-checked!
