Looking for 2c natural diamond for a solitary style art deco ring. I gave jeweler I am working with parameters for H color or better, ex3, faint or no fluorescent and VVS (maybe VS1).

The jeweler I am working with is looking into a GIA certified 2.01c H VVS2 ex3. Faint fluorescence and two small pinpoints and small needle on clarity.

Details:
8.01-8.05 c 4.98mm
Depth 62.1%
Table 59%
Crown angle 36 degrees
Crown height 15%
Pavilion angle 40.8 degrees
Pavilion depth 43.0%
Star length 50%
Lower half 80%
Girdle medium to slightly thick faceted 4%

Comments: internal graining is not shown.

HCA 3.9

This is new to me so I’m not sure how to eval the proportion values but HCA would suggest it is very good?

Also, thoughts about the “internal graining is not shown” comment? From what I can tell this should not be an issue in a high clarity diamond such as VVS?

Any help or input is much appreciated!
 
This isn't a stone most folks here would recommend. HCA helps weed out stones that aren't great. Numbers above 2-2.5 mean "reject". Are you open to alternatives? What is your budget?
 
@lovedogs What are your thoughts… I find it interesting that the mm is only 8.01. That is on the small size for a 2ct. The depth is not of issue and with such a large table it would have spread. Any ideas? Thx!

It's top heavy. 36° CA with a wider table = more diamond material above the girdle than what we're used to seeing with SICs.

I understand that… but it would make one think the mm measurement should be larger than 8.01mm!
 
I’m still not understanding if it has the too heavy wider table why that 8.01mm wouldn’t be larger but I appreciate you taking the time to try to explain it to me.
 
I'm definitely not a math expert so deja is better for this than I am!

Think of it like a liquid filled rubber stress ball: squeeze it in the middle to shrink the diameter, the top puffs out because the mass remains the same but has to go somewhere.

I appreciate the help! Open to other options for sure. Budget for those parameters seems to be about 24K but have som flexibility.

At the end of the day we are looking for something that is going to “look nice” and I am trying to separate out wanting something that is excellent on paper with some of the prices (10k more!) that I see that are much higher vs something that is very good and to the untrained eye will look great on a ring. Hope that makes some sense?

I figure staying in the excellent cut with near colorless and good clarity should safely be in the “looks nice” category?

Is the internal graining anything to worry about in a high clarity grade stone?
 
Are you open to other vendors or flexible at all on color and clarity?

Here are several recommendations that would all be superideals (so, cut to a standard over and above GIA 3x). They’re all from a vendor called Whiteflash and they have an amazing upgrade policy if you ever wanted to go that route.

This would require a bump in budget:

This one is an I color if you are flexible on color at all. Color is extremely personal. Some people see warmth and others do not. Some who see it do not mind it. I have a Whiteflash diamond in an I color and it is white to me.

Sadly, staying in XXX cut isn't going to be "safe" because GIA X is so broad and includes some unfortunate stones.

We can definitely look around and find a better option!
 
Passed on the diamond I first posted based on everyone’s advice and we are looking at a new one with a HCA score 0.9 excellent in all categories.

GIA, 2.02c, I color, VVS2, XXX, no fluorescence

Details:
8.15-8.2 x 4.92mm
Depth 60.2%
Table 59%
Crown angle 34 degrees
Crown height 14%
Pavilion angle 40.6 degrees
Pavilion depth 42.50%
Star length 50%
Lower half 75%
Girdle medium to slightly thick faceted 3.5

Small sacrifice going from H to I color but seems like a better option.

Negotiating price but hopefully for ~24K.

Appreciate the input!

Are you committed to working with the jeweler you mentioned in your first post? Or opposed to buying online? There are a few really good options linked above. @lovedogs posted two really nice ones.

I would say I am fairly committed to working with the jeweler. He is designing the ring setting and I have worked with him prior (my wife’s original ring 10years ago) and was happy with results. He is independent and purchases directly from a supplier and with commission still has prices on par with online suppliers. Still more comfortable seeing something in person before committing to such a large purchase. That said, I have sent him many of the suggestions offered here and we have fine tuned the search with example being the 2nd stone I posted above with HCA of 0.9 with great clarity and acceptable color (I as opposed to H). Thanks everyone! I had no idea I would end up down the rabbit hole so much with this but it is fun to learn new things!
