Yay I was hoping it was!!!
I don't know much about it, other than it's a G, SI1, around 0.39 carats.
The setting is white gold and the ring is circa 1920s.
Honestly, without a head-on pic it's hard to say for sure, but the table is biggish for an OEC. It looks like the faceting is a little chunky, but the culet looks really small- my guess is a later OEC or a transitional.
