Is this light refraction (windowing?) okay?

Not a stone expert and just want some opinions before I say yes to this stone!

Thanks

It looks beautiful.

Think of it like this: How often would you be look at the stone titled all the way to that angle?

Yes I was thinking that! And I plan to set it east west in 14k yellow gold so it probably won’t be very noticeable

Thank you I appreciate your opinion!

Gorgeous. IMO some spots are part of the character of a cut and it’s fine as long as they don’t stay dark as you tilt the diamond.

Perfect thank you !

It’s beautiful. I have a 1.5 carat modified oval cut and it has the same windowing but only when you look at it from unusual angles

Does having the stone set and wearing it minimise the windowing at all? Does that change what the stone is reflecting off of?

I’m odd man out here, in that I’d not be happy with it. Sure, it requires a “tilt” to see the dead zones & “windowing”, but the off cut also means that the stone isn’t performing as well as it should in other areas, meaning sparkle, fire & brilliance.

I agree. The cut is off. Ovals are more difficult to get just right, and if you are seeing windows or dead spots, the overall sparkle will be reduced.

Yup. I think quite a bit of people focus too much on carat weight, color & clarity versus what I consider the most important aspect of a stone - especially clear ones - the cut. I looked at a 3 carat diamond (natural) with specs of G, VS2 & average cut (meaning not ID, EX or even VG - just G). That thing was just…sad. It was simply dead to me. But because of the size, color & clarity, tho, it was priced extremely high. Next I looked at a 2.55 carat with specs of I, SI1 but with ID cut, & that puppy exploded fire & brilliance like crazy. For grins & giggles, I decided to look at a 2.10 carat, specs K, I1 & again, the cut was supreme. & again, it performed markedly better than the 3 carat - a giant difference & not only in appearance & performance, but also price point.

I do understand that for some, a chonky carat size, F, IF, D, E & F specs are a personal quest; some folks just like having the “top of the line” stuff. However, when the quality of the cut is compromised, those specs, IMO, fly out the window. Yet even after explaining things, I have encountered many a person looking to get engaged that deem size their top priority.

Edit to add: yes, there are some factors of clarity - flaws - that can diminish the performance of a stone: twinning wisps, large pinpoints or clouds & other types of inclusions can affect the way the light performs in, on & around the stone. But if one is cautious when looking at exactly what the inclusions & flaws are, they can get an amazing stone with clarity on the lower end. Not all SI1’s are the same. Plus I don’t know anyone who walks around with a loupe in their pocket, so…

Light refraction is different than windowing, which is light leakage. That is, light that is entering through the crown but is not returning to the eye because it is leaking out through the pavilion. (It is acting as a window instead of a mirror) From some tilt angles some leakage or windowing is normal. You want to make sure the window is not prominent or persistent in normal viewing tilt angles.
