What cut is this?

I know, the quality is terrible, I appologize. Thank you in advance

Difficult to tell.
Could be an Old European or transitional cut, depending on the age of the stone.
Hopefully, someone with higher skill
Levels will chime in….

Not a good enough pic to call it.
First thought is a deep pavilion large table MRB but could be wrong.

99% sure it's an RBC with proportions and angles well outside of PriceScope recommended and AGS Ideal.

Thank you, all! I'm an antiques girl, so my biggest loves were butchered by hand under a gas lamp in the early 1800s, so definitely outside the ideals I wonder if this might be from the 30s/40s, I'll try to find out more.

This is a round brilliant with a 42.5 degree pavilion angle and probably pre 2000s but nothing older than 1970.
