It depends on the particular oval and the cushion. Some stones are ovals are cut deeper, and may face up smaller than a cushion of the same weight- and vice versa.

I thought in general the oval was supposed to face up larger, though![]()

Especially when we're talking about fancy shapes, variations in individual examples can be huge.
Not all marquises face up large either.
Like so any other things in life, each of us must be judged not based on the group to which we belong, but our own virtues. It's true for people- and diamonds!
There's some really chubby ovals and some spready cushions.
Rockdiamond|1377482632|3509751 said:Yes, IMO totally off base. Generalizations have no place when people come looking for accurate advice on diamonds.
I look at so many cushions that are larger than ovals of the same weight- so even the assumption about averages is unfounded. This is especially true nowadays since cushions are in much higher demand than ovals, so more rough that might be cut either way ends up as cushions.
By advising people based on averages ( that are not even known to be true) it can lead them to avoid things they may really want, and drive them to things they desire less. That's not fair to people who come looking for accurate advice IMO
"Oval cuts generally look larger from the “face up” position than other shapes of the same carat weight. "

Many cushions and less- but still a lot of ovals
What you are saying about ovals generally being larger than cushions does not hold true based on my real life experience - even as an average
Plus there are no agreed upon standards for either cushion or oval when it comes to declaring either well cut
It is my honest opinion that giving out generalizations is not in the best interest of people coming here looking for accurate advice about diamonds.

I don't agree. If you look purely at face up size on the hand to my eye ovals of the same carat weight (say a triple ex GIA oval versus a triple ex GIA cushion) look bigger on the hand to me. That is all I am saying.
Rather than bicker about it, the poster should go and look at some for himself or herself. Then THEY can say which one their eye prefers....

I fully agree the OP should see them in person because other than size, it would be nice to know who shape is perfected.
But I'd like to continue this discussion. Because I was under the impression that a well cut 1 ct cushion had between 6x6 and 6x 6.5, but a well cut oval was more like 6x8....its a fairly widely held belief on here that oval face up bigger, so if we are collectively wrong, we should know.
Rockdiamond|1377534144|3509964 said:Thanks Neil,
There's actually two discussions here:
1) Is an oval larger than a cushion
2) Whats the best way to advise consumers?
About number 1. If I'm buying a colorless oval, yes, it will typically have a larger appearance than many cushions.
Isn't this what has been stated ad nauseum?I'd bet that a good 95% of posters are indeed referring to colorless diamonds unless they state otherwise. Maybe this should have been clarified with the OP before you insisted that everyone else was "totally off base."

This is NOT the case when I'm buying pink, yellow or brown ovals. When buying Fancy Colored Oval Diamonds, the considerations are totally different- and many of the most attractive stones are not that spready and may appear smaller than a cushion of the same weight.Furthermore, when I buy diamonds, I look through many stones to pick the ones we will buy- I can again stress that as an average, ovals are NOT more spready ( larger looking) than cushions nowadays- in the best cases, yes, but that's by no means an average
But discussion 2 is inexorably wrapped in this answer- for example the OP did not mention colorless or fancy color. You are right, RD. The OP didn't mention this... but neither did you while giving your expert opinion -- until this last post.
If people want advice from non experts * I'd be interested to know your definition of expert and non-expert. Do you consider all those in the trade an expert, such as yourself? Do you feel all those not formally in the trade to be non-experts? I am in no way an expert, but I have spoken with many in the trade that knew way less than most of the veteran PS members I've been following on this forum.
...they're getting it at the mall, big box store- and unfortunately in many jewelry stores.
This is why I am so committed to providing expert advice, in a manner that is more transparent.
For example: many people are given advice in jewelry stones based on the seller's desire to sell. This is true, but that's probably why they come to PS to educate themselves more so that they are less likely to be taken advantage of...
If the store has a cushion they want to sell, they can say cushions look larger for the weight.
What if they have a dumpy "roval" that looks much smaller than a cushion of the same weight- then they can whip out the fact that "Ovals look larger than cushion"
Again, not one poster has said this was a fact. It is a generalization and has been presented as such throughout this thread. Sellers can really say whatever they want, but if the buyer is educated and knows what he likes/what to look for, then what difference does it make which stone faces up larger for the carat weight? If buyers are educated enough to know that ovals tend to face up larger than cushions, then that may lead them to go, "Hmmmm... wonder why this one is smaller?..." At this point, they can do further research and/or seek the opinions of those on PS. We have eyes and we also have access to many online sites to compare (let's not forget PS!!). Someone can tell me all day long that the dumpy "roval" is smaller than a cushion of the same weight, but if I like the dumpy roval... then that's what I like. If I've studied up, then I know I can do a search of an oval that has the same look and try to figure out the "hows and whys" of it all. If the cushion happens to be smaller or larger than whatever, and I want a cushion, then guess what??... I'll probably do some more research.![]()
That's why I feel generalizations are a detriment if folks want accurate, expert advice. I totally agree with you if the question is specific and/or the advice given is specific. Neither of which happened until the last post. Actually, the OP never gave any specifics, which lead us to believe that the OP did indeed want a generalization.![]()
kathley|1377540180|3510010 said:Hi Friends,
I too did the area of the oval and cushion cuts calculations. Area of the oval is pi * r1 * r2. The area of the cushion is roughly (would not account for rounding of edge) l * w assuming the measurements given are length and width; not edge to edge and tip to tip. Results were ave. of 32.70 mm2 for 1 ct. ovals vs. 31.98 mm2 for 1 ct. cushions. If Rockdiamond is selecting ovals and cushions for his inventory that will likely sell, then perhaps the rough results in calculations for his inventory will be slightly different than those randomly measured online. For me, it makes the most sense to see the diamonds of interest before purchasing.

AMEN, kathley... Amen.I appreciate you doing more proper mathematics on this -- a random sampling is just so... well... random.

Looking at online samplings has very little bearing on the way I get to see stones- in person, from cutters, and en masseFurthermore, when I buy diamonds, I look through many stones to pick the ones we will buy- I can again stress that as an average, ovals are NOT more spready ( larger looking) than cushions nowadays- in the best cases, yes, but that's by no means an average
Rockdiamond|1377543160|3510038 said:We can't use geometric calculations accurately at all- because of corner size, LxW will not give an accurate surface area- particularly with ovals and cushions which can vary on shape in a way LxW can't document.
Plus, the sample size and selection is simply not going to allow any substantive conclusions to be drawn.
Basically as a professional it's simply irresponsible for me to give a general answer that overlooks what my experience has proven to me.
That's why I'm here- to clarify things as opposed to the typical answers consumers will get from a person without experience.
Msop- you bolded the part of my statement about which oval I will buy.... but left this part out

but we all agree, stones must be seen to be evaluated-
Although we may disagree about what the correct and professional manner in which to advise people asking, and I do believe everyone is giving what they believe to be helpful advice- there is no offense intended to anyone posting.

Well said! I too have been following this and have learned from it. What's that crazy expression... "Never assume, it just makes an.." - yup, that's the phrase! - I also "assumed" the same that an oval would face up larger, so I am very glad that we were able to learn from David - who is an expert in diamonds.
I also agree with your suggestion to get as much info from the OP as possible to learn what they are thinking/the direction they are headed/any budget constraints, etc., so we can all help in a knowledgeable and informed manner and give the OP the answers they are looking for.
I too feel like sometimes people get swayed or thrown off by posts that are written with the best of intentions, but can get blurry. AGain, like you, that's just my 'behind the scenes' observation of several threads in the past few months. I'm sure I've been an unintentional "blurry poster" too!![]()
Any how, well said Christina - very well put and I find I never stop learning on this site! Yay to all of us who keep coming back for more and more knowledge! -- and to the trades people who are so generous with their input.
