I have been searching far and wide for this ring. I love it and cannot seem to find it anywhere. I am a ring collector and this would of been my dream ring if I had ever gotten married. Can anyone identify where to buy this?
While I can't identify who made that particular ring, you are looking for a marquise in a halo setting with channel set shank. Perhaps this will make your search easier. I did a quick search and couldn't find the combination of the halo and channel set shank. Channel set seems to have fallen out of favour, being replaced by pave set mellee. Part of it, I guess, is that it is visually closer to the way the halos are set (tiny beads and tiny prongs).
If you don't find a ring ready made, you can also have it custom made just the way you want it.
