My guess is OWD by looking at the picture.
What is it specifically you are wanting comments on, OP?
A lot of comments I would make would really depend on what it is you are looking for/what’s important to you - to see/have in a OEC/ring
I love that stone.
You bought from a specialist, if you're worried about being ripped off, you weren't.
You did well. OWD is famous for their procured inventory of old cuts.
Yes, is it possible with a lot of legwork, time, and luck you might find some auction somewhere for a little cheaper? Could be. Maybe. I wouldn't worry too much about it.
Rest assured the ring you bought is absolutely beautiful. Are you as enamored as I am? Do you love it? That really is the only question that matters.
* We require pictures, many pictures! We all would love to see this beauty up close. We love video too
Gorgeous! I loved this stone when I saw it on OWD's IG and I love seeing it in the setting you've put it in. It's really elegant and beautiful. Congratulations!
