Is this an OEC diamond?

Hello everyone,

I was hoping someone might be able to tell if this center stone is an OEC. It was my great grandmother's. I don't have many details, but know she was married in the mid to late 20s. The local appraiser we took it to said it was OMC, .35 carat, I1 clarity, and G color. The diamond is not perfectly round, but I was under the impression that OMCs were a little more squarish than this. I'd love to hear your thoughts.

I have a couple more pictures, but unfortunately, my camera is just a simple point & shoot.
 
<bump>

Maybe someone can explain what's the difference between an OEC and an OMC? I've always wondered...both have high crown angles, right?
 
mynattk-sorry, I can't help you ID, but I just wanted to say that your great grandmother's set is beautiful! that's so neat that you have it.
 
thanks very much : ) It's not as big as I imagined I'd have when I was a little girl, but it sure does sparkle in the elevator on the way up to the office! (oh, and at church. sometimes I feel like I should just take it off to pay better attention to the lesson.)
 
I can't see clearly the facet structure so I couldn't tell you OP but if you can get a clearer closeup of the diamond when its really clean that would help give us an idea.

Antelope1 the difference is in the girdle outline Old Mine Cuts were most often square or cushion shaped following the shape of the rough. OECs have round girdle outlines.

See more in the article I wrote 4rth paragraph.

you may want to post this in Timeless Classics, there are several knowledgeable ladies who could most likely help there :))
 
Thanks ChunkyCushionLover and Yssie. Very helpful links and advice. Someday I will own a camera that can take better macro photos! :tongue:
 
judging by the looks and the girdle it looks like to me an oec that was repaired at one point.
But without looking at the diamond in person it would be impossible to say for 100% sure.
 
It appears to be a borderline between an Old European cut and a modern cut. A bit of an older version of what is often called a "Transition Cut". It is not cut in the style of today's modern cut diamonds, yet is shows evidence of more modern proportions than many Old Euros show. Hope this helps you.
 
Wow, I am gratified by all the expert opinions here. I have been reading on this forum off and on for a few years now and looked at many posts about antique cuts. At the risk of sounding silly, having you all comment on my post is almost like finally getting to talk to a favorite radio personality or celebrity. It's a privilege to have access to so many knowledgable and helpful people all in one place. Thank you!
