Hm, it definitely belongs to a PS member - I remember seeing it and admiring it on one of the east-west marquise threads. Aha! Found it: MAChick''s custom made setting, here: https://www.pricescope.com/community/threads/my-new-ring-custom-from-greenlake-jewelry-works.45126/
Ahh, that''s where I found it. I have a gazillion pictures downloaded of rings that I really liked ,and sometimes I can''t remeber where they all came from.
Thanks for the link. I never got to see the finished product until just now, only that one picture. Lot''s of possibilities, thanks again.
