Is this windowing?!?!

[mazymae]

Please help. I received this antique cushion for evaluation of an online purchase. I’ve been reading enough to think that this may be windowing? It seems like I can see my skin through the center part and I can see black through it when it’s in the box? Is it supposed to be that way? Is this a fatal flaw?

maybe its a bowtie
they can happen with some antique cuts
i think back in the day they were not viewed as a negative

Huge amount of leakage, yes a fatal flaw to appearance and performance.

Thank you. I’m so sad. I can even see this hot pink box through it.

Help me check the parameters of this diamond to see if it is super ideal cut or excellent?

Hi All!
Important to keep in mind:
Longer shapes tend to have longer facets. When you tilt through a range, it will cause “windowing”.
Also- this is not a valid test if the quality of cut- especially in cases of antique style stones with larger facets.
I assess stones by looking at them under normal conditions as opposed to putting colored paper behind. And I totally understand why consumers might assume these things have meaning based on online research
