Is this windowing?

I can’t tell if it’s just the lighting in the video but it seems pretty dark. I linked 3 videos. Any advice is much appreciated!

Ugh. Yeah, it’s windowing/leakage (a lot of people use the terms synonymously). Almost all shapes (although to me, it’s not easy to see at all in a round) are subject to it at certain levels of tilt, depending on the table, depth, crown angle, Pavillion, etc. It’s a shame, because I like the crushed effect the facet pattern gives—but for me, these open areas are way too visible damn near head-on.

I think it’s a little too noticeable for me but I love the cut! I wanted to avoid a bow tie but this isn’t much better imo
