Wow - that is pretty! It seems to accentuate the diamond from the sides of the band more than a standard tension set ring.
I think that the point might be a little too close to the finger - it seems like once it's on your finger the point would be a point of contact....
My other concern is that I would accidently hit my hand against something from the top, and dislodge my diamond (maybe spearing my hand in the process!)...
I am looking into tension settings, however, and would like to hear a little more about this particular setting because I do like that it really emphasizes the diamond from all perspectives...
