first let me say the ring you posted is TDF!
but truthfully, i feel as though i have seen your setting countless times before. so my question is: how important is it for you to have the name kotlar attached to your ring. most ppl don't ask who designed your ring, but most will want to get a closer look at it and congratulate you. KWIM?
it's a decision that you will have to live with so it's hard for me to say which route you should go. and considering how involved you are in the process i think you should focus on what's really important to you.
GL!
Thanks for your compliment and your comments.
It is true that in concept, this ring has been done by many others (Cartier, Harry Winston, and many non-branded designers). The clincher about the Kotlar ring is not the brand (which I hadn't heard of before seeing this ring), but the craftsmanship visible in the hand made mounting (with handcarved seats for each tiny diamond in the halo and band, the delicate basket under the diamond, which unfortunately you can't see in the photos) that sets this ring apart. In person you would see and feel the difference. Its a pity I don't have photos that show it!

Anyhow, thanks again for your advice!
I'm leaning toward option 1, despite all of this. But I'll keep all of you posted. More diamonds are coming in this week. If I find one that I love then that will likely seal the deal and I'll go with option 1.
