Can anyone give me some insight on this SI 1 stone? Thinking about purchasing. Looking at it today and have only seen the specs so far. Are the twinning wisps an issue?

3.0c, Round, J SI 1
Cut: Very Good
Polish: Excellent
Symmetry: Very Good
Fluorecence: None

Crown angle, pavilion angle and depth aren't good.
 
Is this going to be incredibly noticeable? Would you pass on the stone if it were for a great price?
 
If you aren't looking for performance, just for size, it won't face up as a 3 ct due to 65% depth. You might want to list out its price so that more experienced PSers can further advise you.
 
Hm, so you're saying it will look much smaller than 3c? It's pricing at 21k.
 
It scores a 2.1 on the HCA - which is a good score, but with that depth it will face up smaller than an ideal cut stone will. It won't look like a 3ct stone. I'm no expert but I'll bet the crown angle is offsetting the deep depth (steep/deep).
 
Thank you very much for the insight. I'm going to see the stone in person today so I guess I'll compare it to a more ideal 3c and see if the size difference is really noticeable.

Do you think 21k is a fair price for it?

aa725, I would pass on this stone due to the cut grade (not being excellent) and the depth... it's going to face up smaller than a 3ct. You could get a lower carat weight stone that will appear the same size, if not larger than this stone.

Also, have you seen J color stones in this size before? Even an excellent cut J will show some tint at this size (and a good bit of tint from the side). I would imagine a lesser cut grade would show a more tint from all angles.

There is nothing wrong with a J (I have one, but only at 2.4 ct and XXX -- and it doesn show tint from the side)... however, you'd be better served to have seen an excellent cut J in real life (not just under the "magic lights" of the jewelry store) -- to make sure you're okay with the warmth. If the setting will not expose the sides, then going with a lower color such as this is a great way to maximize your budget! :))

On a positive note, it scored a 2.1 on the HCA, so that's not bad at all. You would want to shoot for <2, but it only got a subpar score on the spread (how large it should face up).

What is the "great price" they are asking for this stone? If you feel comfortable telling us this (as well as your budget, if it's different), maybe someone can find a better stone for you. :)) It's only a good deal if you get what you want.

EDIT: just saw price @ $21K :mrgreen:
 
What are the LxW dimensions?

The stones I'm finding online with the same specs are much more expensive. The prices I'm finding online are about 20-23K for GIA VG cut, I/J, SI1/SI2 stones in 2.5 carat range.

Honestly, I would be hesitant for a 3 ct at that price. :?
 
I would ditto what others have said and add that if it is a 3.00 carat stone then it was probably cut to retain that three carat mark rather than excellent cut. Do you have an IS scope to take with you? I'm betting there is some light leakage in the stone.

Only you can decide your main criteria: price, size or cut quality. I'd personally be looking for more of a balance in a stone than this one seems to have.

Bigger, better, but more expensive

I am sending this so you can see the loupe feature, the ideal scope pictures and all that. Compare it to the cert, too. Good source of information for certain diamond at b2c.

This looks okay, but the HCA score was 3.7... The photo looks pretty good, but I wonder what it looks like IRL?? I'd be interested to see it for that price though. ;))
 
Appreciating all the insight/advice, guys. Thanks.

The dimensions are 8.88 - 9.04 x 5.82 mm.
 
Forgive the hijack, but I am curious. How does a depth of 65, which is really deep, allow a diamond to get a 2.1 on the HCA. I would have thought it would be much higher? Are the angles somehow helping it?

I couldn't believe it either, ruby59... :shock: :confused: I ran the numbers like 4 times because I thought I'd screwed up somehow... Since the only parameter that didn't score very good or excellent was spread, maybe the high crown angle kinda helps when paired with the depth, making for just a really high-crowned, deep stone?? Maybe someone with more knowledge can explain this to us.
 
Granted my stone scored a 2.6 on the HCA (blasphemy!! :lol: ), it is 8.7mm at 2.43 ct. With a 3 carat, I'd want to at least get in the 9.2+ range. :bigsmile:

OP, if you don't mind disclosing your maximum budget, that would be helpful. :))

Does anyone think this would be noticably off round? (didn't know if the difference would affect it or not at this size...) :read:
 
You should probably have it sent to an appraiser.
