Please help identify my heirloom diamond

[alloamie]

This diamond was passed down to me from my grandmother. My mom had it made into a pendant for me as a wedding gift.
I''m a total newbie at this, but would love some help in seeing if it''s possibly an older cut? or is it a modern RB?
Unfortunately, I don''t have any stats on the stone. Thanks in advance for any opinions!

my pics aren''t the greatest, but hopefully they''re clear enough to get some feedback!

I can''t help with your question too much - it does not look like a very old cut. Perhaps it is transitional? I''m sure that the more knowledgable PSers will chime in.

It does look beautiful, though. I love the bezel setting.

Looks like a round brilliant to me. What a sweet gift from your mom! Very pretty!

Of course it''s hard to be sure just from a couple of pics, but it does look like a round brilliant

i was thinking it is probably a RB, just being hopeful that it might be an antique!
