Hi All! I don't know anything about cushions yet and was wondering if this is a good diamond based on the numbers. I have a "cheat sheet" for rounds and am wondering if there's one for cushions so I know what parameters to stay in for depth, table, etc.

Thanks in advance for your help! 8)


Shape:
Cushion
Carat Weight:
2.07
Color:
I
Clarity: VS2
Graded By GIA


Depth: 68.60%
Table: 50.00%
Girdle:
Thin to Thick Faceted
Culet: Large
Polish: Excellent
Symmetry: Very Good
Fluorescence:
None
Measurements: 7.47x7.47x5.12 mm
Ratio : 1.00
 
No way to tell based on the numbers. Need images/video, ASET images, etc. to know for sure that you are getting what you want. Some prefer the more modern cushion brilliants while others like the antique/vintage chunky cushions.
 
Based on those specs, looks like you're looking at an older stone, or at least an older style (large cutlet). Also, kudos on finding a PERFECTLY square one (not my taste, but a hard find none the less).

I was told by a respected cushion expert that 'ideal' depth is in the 62-65 range, but you aren't outside of parameters that I'd consider myself (I'm shopping ~2.5ct+, same color/clarity).

Keep in mind that the very low 2cts (2.01, .02, etc.) tend to be cut for weight and not for actual performance. I've found some very beautiful stones in the 2.20-2.4 range that are cut MUCH better than the lower and higher weights (2.02, 2.52, 3.01, etc).

Ask the vendor for photos and ASET images, if not available, see it in person (maybe by buying and taking advantage of a return policy), or move to another vendor.
 
Is it bad that the culet is large? Does that mean there is more weight in the culet then there ideally should be?
 
I think it is a pretty stone. I wouldn't look at any stones that didn't have pictures because cushions vary too much in appearance. Large culet in this case means that it is an antique cut cushion that has a fact cut on the culet instead of coming to a point. Therefore you have a flat surface for the culet. I love them, personally!
 
Hi Sarah,
I can't answer any questions about a particular diamond from a vendor- but I can answer general questions:
1) There is no "ideal" range for table depth or any other aspect of a cushion diamond.
2) sometimes a stone just happens to get cut and end up 2.00cts.
I agree that there are cases of 2.00ct stones that should have been cut to 1.90- however the mere fact a diamond is 2.00cts, does not mean it's been cut to save weight for that reason alone.


I know there's a lot of information out there- but a lot of there are different experts, with different opinions. Basing judgement of a specific stone, on generalities is not helpful to the person looking at the given stone.
IOW- if you ask a trusted vendor if a given 2.00 is cut to deep, and you trust them- you will get a relevant answer.
But if you limit your search to exclude stones of 2.00cts for this reason, you may eliminate some promising candidates.
 
1. Please toss that cheat sheet for rounds. The only good use I've seen for it is giving it to your insurance company to restrict their search in the event that you make a claim.
2. If you ever come across a nice, simple, easy cheat sheet for any other shape, toss that too. Unless it's written by a PS poster named CCL and has a discussion thread twenty pages long attached, in which case read all twenty pages of discussion and disclaimer info before actually using it ::)


I don't like that cushion, but I loathe "mush", and that stone has nothing but under the table. I have found good photos (which this certainly looks to be) to be quite accurate in diagnosing Mush, actually, so... I'd keep looking, personally.

In defense of my statement, the 'ideal' range of 62-64 came from someone who authored AGS standards. Again, I'm looking outside of that range too, but I'd absolutely kick a cushion with depth over 70 or under high 50s.
 
Hi TGT!!!

Thanks for responding- please understand that my position is delicate....I've been confronted, many times, with statements made by other experts that I disagree with. AGSL cut standards for fancy shapes do not enjoy broad acceptance.
Please understand that I never want to put anyone in the position of "justifying" something they've been told by someone else- that they believe.

I've been "surprised" by many stones. What I mean to say is that there have been many occasions that I've been looking at stones- and one that has an "extreme" number comes up- say depth of 50%.
Although there is a "common sense" that dictates there's going to be some glaring shortfall in that stone, I find it's actually very attractive.
Or, a stone with higher depth that surprises me due to a high crown that makes up for the depth producing a very attractive stone that does not look all that small for it's weight.
Based on experiences like this, I'd say it's shortsighted to eliminate a stone based on narrow parameters.

Having said all that, I hope I did not insult you at all with my post.
 
For myself, I have found that cushions with the following table and depth ranges tend to look better. Personally, I believe the diamond you found is not bad at all for a generic cushion. The facet pattern is pleasing. Is the stone going to be as bright as an AVC? No ... but again .. the price reflects that. Do you have an opportunity to see it in person?

Table: Anything below 56%
Depth: 63 - 69%
 
Thanks everyone for your help! 8) My brother is the one who would be purchasing this stone, it's for his fiance's engagement ring. They are looking for diamonds together and both really love it in person. Since I can't see the stone in person, they've been emailing me for advice. I just want them to have the best possible diamond for their money, so I'm nervous about them making this purchase. They feel comfortable with the vendor and I think they already have an emotional attachment to the diamond.
 
What is an AVC?
 
The 3 JA stones are ok but just going by visual appeaerance - I think the ERD stone looks better in terms of shape and face pattern. It might be not as bright but a small margin but I doubt the ASETs will look signficantly better. Note the ERD stone is also a fair bit cheaper than these 3 options. Maybe I am feeling cheap these few days .. but that price is very attractive to me especially with the balance of the quality of the stone they are getting.
 
Farmer gal, thanks for recommending those cushions, but unfortunately, those are out of my brother's budget.

CharmyPoo, thanks for showing what an AVC is...there is quite a premium, but it's a beautiful stone.

I think they're in love with the diamond they found and also are exhausted after looking at as many cushions as they have.

Thanks to everyone who replied to my post. Pricescope is a wonderful community.
