Holloway cut advisor question

[cashton13]

Hi everyone, can anyone explain the holloway cut advisor. I understand anything less then 2 is excellent, my question is a 0.9 better then a 1.3?
Or is everything under 2 and excellent treated the same? I'm aware that this is not a diamond selector more or less weeds out the bad ones. Thank you

Grrrr the whole posting links thing is absurd - I can’t even link a page on this website!!!

Anyway - on this website there is an HCA page - go there and Scroll down to usage notes.

A lower score does not necessarily mean ‘better’ once below 2

Thank you , would you say it's better to go by ideal round dimensions then? Or is the only real way to tell the aset scope?

Are you talking about the LxW? No, that's not the way to evaluate a round stone.

Under 2 for the HCA means its worth further review. An ASET scope tells you what exactly is going on.

As @MackPUK stated, 0.9 is not better than 1.3 (or vice versa).
Here are 2 of the notes under the HCA tool

• Most people prefer diamonds scoring 1.0-2.0, or top Hearts & Arrows diamonds up to 2.5 for rings
• Diamonds scoring below 1.0 may be more suitable for earrings and pendants than rings.

Thanks , no I was referring to table, crown height, depth and so on.

It's a starting point, but does NOT guarantee a great diamond (which is why there is a notice that says along the lines of "should sparkle nicely...verify with ASET")...bear in mind that the HCA is a mass reject tool, not an individual selection tool. No cut estimator site will be able to assess material/crystal quality, characteristics of any inclusions, the finer details of cut precision, and the optics of any diamond.

The broad purpose is to eliminate all the potentially bad proportioned rounds to leave a smaller amount of *potentially* great diamonds - a smaller amount of diamonds to go through and assess, further narrowing the field until you have a short list of frontrunner candidates to make a final selection from.

Understood and well said thank you. Looks like an aset scope could be a good investment then.
