I am in love with the look of a simple oval diamond in a platinum bezel head on a yellow-gold band. We have such wonderful tools to help find an ideal cut round, but an oval isn't so easy. Of course, I want to avoid a bow tie. Please, kind Pricescopers, what links or sites should I go to teach myself about finding an excellent oval diamond?

Distinctive Gem and Jann Paul have developed their own “ideal” ovals, to avoid some of the common pitfalls with the cut. You could review some of their YouTube videos to see what they say about the features they tried to include/avoid.

Thank you. I’ll do that.

How interesting! The ideal cut ovals in Paul’s videos certainly seem to look “wider” than a standard cut oval.
 
Unfortunately, I dont know of any. I have done a deep dive on ovals and can tell you what I've learned.

Remember, the purpose of a well-cut stone is to reflect light back to your eye. Light comes in through the table/crown,
bounces around, and returns out the top of the stone to your eye. The less it bounces around before it comes back out
the brighter the light will be. As it bounces it loses light so the more it bounces the weaker the light return to your
eye will be.

Ovals come in several different faceting patterns. You can see the faceting pattern by looking at the clarity plot pavilion (bottom)
diagram on the GIA report.

Ovals come in 4 main, 6 main, 8 main, 8 main offset, and 10 mains. The typical faceting pattern (what you see mostly) is the
8 main offset pattern. 10 mains are usually Branded stones. You can find good and bad ovals of each of the different
faceting patterns but in general*, I find the 6 mains and 8 mains to have better light return.

This is a typical 8 main offset facetting pattern. The green areas are "nice" facets that will return light nicely. The brown areas are
typically "mushy" areas that do not return light well.

It's important to pay attention to how the stone performs as it moves (turns). You want more "nice" facets to pop-up under the
table. This is a 6 main that shows nice facets popping up as it moves...

Hopefully, that's enough to get you started. I'll be happy to answer any questions you have.

Btw...here is my favorite type of oval...although they tend to be more expensive. Most branded ovals are more expensive
because they have to cut away more and have to be more precisely cut.


Also, you can look at this thread, post #17 for reference to the different faceting patterns of an oval. I've posted
the GIA reports for the different types.

My goodness. The Aster Oval is amazing! Thank you so much for your valuable insight. I also appreciate the information on the different numbers of "mains".

Yes, the mains give ovals different looks and also affect the light return.

You have any pictures @Heathcat24 ? We'd love to see some!

I take such horrible pictures! Lol! But this is it between my loose K Quadexes.

I need to try to get some better photos of this oval. (I get so nervous handling these little things loose!)

It really is a phenomenal stone!

That is a spectacular stone!!

Thank you so much! I justified the purchase because they were giving away stamps and a 10% rebate! Lol!

I am sure the larger ones are just SPECTACULAR and if anybody on here has one, I'd LOVE to see it!
 
I think the branded, and Hearts and Arrows ovals are cool!
But, they're also a packaged product.
To me, part of the fascination of ovals ( and many diamonds) are the innumerable variations.
Is a "Moval" bad?
What about Oval Modified Brilliant designs?
I think that when education is mixed up with people selling things....it gets a bit diluted. Theirs is the "best" "never before"..that sort of hype gets in the way of real education IMO.....
 
To add:
Looking back over the thread:
@tyty333 post #4...that IS very educational, with regards to more traditional, oval brilliant diamonds. The pictures in that post are very much in line with what I look for in person.
Not that the sparkle or flashes are "even" from top to bottom- but that the dispersion of light is pleasing when the center of the stone flashes bright.
Personally- I love when an oval looks like an oval - I don't want it to look like a round.
I didn't mean to imply there's anything "wrong" with the traditional, well cut oval brilliant design at all!
Just that there are other, less traditional ovals that will be more appealing to a percentage of buyers.
And bottom line- neither is "right" or wrong. Or better.
 
Oh my gosh, @Healthcat24 they are all so cute! It makes me want one of each of BN's H&A stones in fancy cuts!

What are your plans for setting them?

Edit...and your pictures are pretty good IMO, especially for smaller stones.

What size (carats) are the Quadexes?

Thank you so much!!! I'm exactly like you! I wish I could have some of all of them!

The Quadexes are about .43 or .44 ct each. I have a little Quadex bezel pendant the same size and originally planned to set this pair as studs. But I realized I'd just never wear them!

I've gone through several plans. But I REALLY want a five stone ring! I ran across one a couple of years ago that was a mix of H&A rounds and cushions in a semi-bezel setting that I thought was FABULOUS! I'd love to do something like that!

That really is next on my list. Haha! And I think the oval is going smack dab in the middle...
 
A five stone would be awesome! I would want them in something I could see so earrings wouldn't work for me.
Please create a thread and ping me when you have it made. I would really love to see it!

Sorry for the thread jack @TwoPointSixFourCt .

Ty, I’ve studied and I think I found a prospect. I’d love to hear your thoughts on this stone on my post:

I’d loooove to hear your thoughts on this oval I have on hold.
