You use the HCA as a rejection tool. Aim for a score of 2 or less. The middle stone you posted above has this. After that you should see the stone in person or ask for ASET and idealscope images to check the light performance.

Here is a superideal cut stone in the same budget to compare:

Definitely #2 over the other options. Any reasons for such high color and clarity? I would take the WF stone snowdrop posted that still has a great balance of specs and a superior upgrade policy over these.

yes- and the cut parameters are much better on it. You get what you pay for with diamonds.

Here is a basic video for you showing how good cut parameters help performance:

Yes, my intention was to show you something that has an amazing cut! A G VS2 will face up very white and be eye clean, as it says on the listing. I think the wire price is within the same budget as you quoted?

The stone that Snowdrop posted is a Super Ideal H&A AGS000 Branded cut (ACA). It has been tested for Ideal light return and has all
the images needed to prove that it is a top of the line stone. Wire price is $7985.
