You were right, it is Wed515! Or eng951 if you don't want the matching band.
I love this ring too, but just a word of caution. Another member of this Board has the same setting, and has had issues with losing stones. From what i hear, this just comes with the territory with some micropave rings. You will most likely have to replace stones at some point. Also, I noticed that the orignal poster of this post also sold her ring on the Diamond Bistro recently, although I'm not sure why.
Here is the thread about the stones falling out:http://betterthandiamond.com/discussion/ubbthreads.php/topics/704935/1
And here is a link on weddingbee.com from someone who has the same ring, who absolutely loves hers:http://boards.weddingbee.com/topic/my-beautiful-petite-halo
Haha i stalked this ring for awhile, that's how i have these links.
I say if you love it, get it. It is still in the list of my favorites, even if i do have to replace a stone or two. I have a right hand ring with micropave and have never had any issues. Be sure and post pics if you end up getting it!!
