Hello my friend, not OP, but a collector of old cut stones. Yes, this is an Old European cut stone. Old European cuts are typically like the one in this photo; a small table, visible culet, more depth (so often appear smaller in face-up compared to MRB for the same carat weight, but also leads to unique and enjoyable light return compared to MRB). They have larger/different faceting compared to modern round brilliant cuts, so that they flash light like a “chunky” clearly-faceted cushion cut as compared to a “crushed ice/crushed glass” cushion cut.
Thanks my friend. This is so helpful. I would see women with rings with these stones and couldn’t figure out why theirs looked different but weren’t a cushion. I appreciate it lots
