Do you think this stone is an old cut or not?

I cropped the photo for a closer look but bc of the angle I can’t totally tell. It’s listed as cushion and not specifically old cut and also as irradiated. I’m not very familiar with irradiation of diamonds - are they already low color yellow but done so to enhance the yellow or are they typically white to be made to look fancy yellow?

Not.

Looks like a modified cushion brilliant cut to me

modern
nuked stones start out as browns.
Yellow off the top of my head requires more steps after being nuked.
It also looks like a bad Photoshop job the real color in all probability is nothing like that shown

I’m not in the market which is why I came to PS rather than ask seller for additional pictures! I would love a fancy old cut one day.

Makes sense. I would love an old cut as well, and they've been irradiating diamonds for a long time. Who knows where those lines might intersect?
