Proposal Ring - Part 2

[rickroll]

Well ideally I would like lower clarity but i struggle to find one with good HCA score.

Thanks for the valuable feedback.

 

[Draculav]

I would'nt say HCA 1.6 is bad... but it can be better.. HCA is only to check the basic proportions. You will need to use the ASET scope and Hearts/Arrows scope to confirm it. Without the scopes, the HCA is useless. Even if you get the best HCA score 0.4, it can still turn out bad.

For most of us, you're only going to buy a diamond once in your life. Trust me.. it's worth the wait to find a good one. Don't regret your decision and feel that you only "settled" for one.

Btw, it's a flat 0.40ct size.. Try going for a 0.3X or 0.4X for better value.

Hi can I check for

Gia report: 1177830442 is it consider as a good diamond with respect to the HCA value etc?


Thank you all for the advice.

Bro.. yours is a Solasfera.. the HCA won't apply.
You will need to use the scopes instead.

The HCA can only use on the 57 facets 8 hearts and arrows diamonds.
It analyzes 17/57 facets of the diamond. So for those other cuts or higher facets type, it will not be accurate. That's also why there isn't any crown or pavilion angles written on the certificate for those type of diamonds. So yea... use the scopes

- HCA passes at 1.2
- Diamond depth is too long at 62.6%. will make the diamond appear smaller and highly possible light leakage

0.47 E VS1
- HCA 1.8
- Depth 62.7% (too long)
- Crown 36 degree (too steep)
- Faint fluorescence

0.61 F VS1
- HCA 1.8
- Depth 62.5% (too long)
- Crown 36 degree (too steep)


General guide for depth is to not go beyond 62%, as recommended by many diamond connoisseurs around the world and forums.
Like bro Draculav said about the scopes. they exists for a reason.. till date most pte jewelers still refuse to show the scopes, perhaps too much to hide.

based from the proportions, it is out of the ideal range.. HCA score can be relatively low, but it won't factor in extremities in the angles..
HCA in this instance is an example of being limited in it's function.

Well said bro!

The problem with the HCA tool is that it is only based on 5 inputs. The 5 number inputs don’t take into account of all of the diamond’s facets. The numbers on the GIA certificate may not be accurate themselves because they are averaged and rounded off. If the numbers on the certificate don’t represent the diamond accurately, the HCA won’t pick up these problems.

When you read the description of the HCA, it states that you should use it as a rejection tool and not a decision making tool. That’s also why I don't understand how people buy diamonds just from looking at the certificate.


A good reference is

The poor performing diamond is a HCA score 1.7 btw.

It will be more useful and accurate if people share the GIA certificate AND scope images, then ask for opinions. Half info can only give half advice

Thanks for sharing. Any good guide on diamond propotion?

My second choice would be this.

hi im no expert but i think you should stay away from those with thick to extremely thick girdle. The depth of 73.9% would be way too long and make your diamond smaller.

That's a square diamond?

Yup its an angel cut?

If so this diamond not worth that $$ i will get something else since i plc a deposit

Opps sorry I did not notice the inscription earlier. Im not sure if its the same for that

 

[Grizz.P]

Angel cut need not adhere to the depth restriction.
They are a cut of its own

Like the cushion Brellia is also different.
