Help with hca score

Hi everyone,
I am relatively new here and I am wondering if someone could help me generate a hca report for this diamond. Many thanks in advance

Based on the specs, it would definitely fall between the 1-2 range on the HCA...probably around a 1.4-1.6 score.

It's available at B2C for a bit less:

thanks for your recommendation. I am a little bit concerned about the clarity of these ones. Is vs2 a bit too low for a 2ct rock?

Thank you! That’s not as good as I thought

Not too low at all. Clarity is determined by the types, sizes, and number of inclusions.
For strategically placed inclusions (in the crown area, for example), you will likely never see them without magnification...and that's after you hunt and find them. LGD is quite forgiving, since there are all sorts of inclusion types that can be found in EGD that just aren't present in LGD due to the controlled environment of the growth process.

Thank you! That’s not as good as I thought

It's rated as Excellent per the HCA...the proportions and angles are well within the ranges of what all super ideal cut diamonds would need to be.

HCA doesn't have "better" or "worse" for numbers under 2. It's a rejection tool (e.g. probably reject anything scoring over 2), not a selection tool. So a 1.8 HCA is no better or worse than a .7

lovedogs is right (as usual )

hi DejaWiz and lovdogs. thanks for clairifying. with regards to the last dot points below. does that mean a hca score that is <1 is actually less desirable for a ring?

I have an eye on a 2.08 ct E VS1 rock that has a HCA score of 0.9. does this mean its actually less desirable?

That's a gorgeous diamond, right there!
No need to worry about a well-proportioned diamond scoring slightly below 1 on the HCA, because we know that the proportions and angles are well within the recommended ideal ranges (see link below).
It's not uncommon for some super ideal cut diamonds such as Whiteflash ACA, Brian Gavin Black, CBI, JannPaul White Series, and Victor Canera H&A to score just below a 1, as well.

Diamond Proportions

The physics of light-behavior within a diamond are reliably consistent, which means proportions measurements can be useful.

I agree! Check out this recent thread discussing HCA scores under 1 as well.
