HCA Question

[regularsfguy]

Hi everybody,

When running prospective diamonds through the HCA Pricescope, I noticed this:

"A score below 2 (Excellent) means you have eliminated known poor performers (more than 95% of all diamonds). Your own personal preference may be for a diamond with an HCA score of 1.5 more rather than one with a lower score of say 0.5."

I was wondering what people's experiences have been on this. Anyone who's compared two diamonds in person and found the *higher* HCA score (but still below 2.0) to be better looking in person? Would people recommend that I shoot for a score of 1.5 over a score of 0.5 or 1.0?

Thanks in advance for any help!

Two stones may share the same HCA score and can look very different from each other. The angles are all an average (and then GIA rounds that average) so you just want to reject stones that are over 2.

I'm one eye blind, farsighted and have presbyopia... I prefer shallow diamonds and lower HCA scores, like elderly people often do.

ditto pps - shallow stones often score lower, shallow vs. "too shallow" is a distinction that isn't necessarily the same for everyone.
I had a stone that scored 0.8, it was shallow and had obstruction issues and I didn't like it. My first stone scored 2.5 and I adored it. Another poster Stephan (earlier in this thread) recently purchased a stone that scored 0.4, but the AGS ASET looks picture perfect - HCA is a *blunt* weeding tool and should not be used to positively confirm anything.

Thank you all so much for your feedback!

My head is spinning! I'd appreciate any feedback on the following stone from whiteflash:

http://www.whiteflash.com/loose-diamonds/round-cut-loose-diamond-2372515.htm

I checked HCA, and the stone comes in at 1.5. Also, the ASET image seems fine to me, although maybe there is too much blue and not enough red? I'm not experienced enough to know if it is a good (or even *great*) image.

Alternatively, if people can recommend other stones in that same price range, I'd really appreciate it. Our range is:

RB
1.0-1.1 ct (although if I could sneak it up a little to 1.15 ct, that would be nice! )
H-I color
VS2-SI1 eye-clean
$5-$6k

Thanks in advance!!
