Seeking Oval Lab Diamond with Higher Ratio and Minimal Bowtie

[deep031]

Lots of research leading up to this post but very much an amateur when it comes to diamonds.

I am searching for an oval lab diamond for an engagement ring. We are looking for a carat weight around 2.75 and a ratio of 1.45-1-5. The bowtie of a lot of the stones we’ve viewed has been keeping us from pulling the trigger.

From research a GCAL 8x certified stone may do us well but I have been having trouble locating one at the ratio we want. For instance, JannPaul does up to 1.35.

I would love if someone can point me in a direction!

Hi deep031, welcome to PS.
Bowties are a funny(?) thing....
An oval brilliant- when well cut- will have different size facets at the tips compared to the middle. Are there bad bowties in some oval diamonds? Yes definitely.
The nicest ovals light up bright in the middle......yet if someone is fixated on the difference it might seem like a detraction.
GCAL graded ovals are much more rare on the market...but they do exist.
The aspects of cut I'm speaking about exist in any well cut oval- including GCAL ones that I've seen

Thank you for the knowledge drop! Searching for these well cut ovals is proving to be harder than I thought, especially since now that is all my girlfriend notices at first!

It has been my experience that when someone is very concerned about "bow ties"....it kind of dooms Oval Brilliant, as a cut.
Especially longer taller ovals.
The facet design of an "Oval Modified Brilliant" adds extra facets below the girdle to break up the larger reflections, giving a "crushed ice" appearance.
You see many fancy colored ovals cut in this manner.

If she's really noticing it.....arghh.....consider a round diamond?

A long oval unless cut for crushed ice is going to bow tie.
Its physics.
Even in crushed ice well cut examples are rare.

Edit..what David said above.

Most lab ovals I've seen are cut with 8 mains offset from the center. This causes the more pronounced bow-tie effect.



You can see the 8 main diagram on the GCAL report.


So, like the others are saying...you're going to have a hard time finding a lab stone that is not cut with a bow-tie effect. Especially
in one with a high ratio (the closer you are to round the more the bow-tie can be minimized).

Ovals also come cut with 4 mains, 6 mains, 2 different types of 8 mains, and 10 mains. Some of them minimize the bow-tie
affect more than others so you might try to find some ovals with different numbers of mains (not an easy task).

For example...here is a 4 main. IMO, in general, the bow-tie is not as bad as an 8 main offset configuration however, each
oval has to be evaluated on its specifics.
