P -- nice ring -- now don't take offence a proper appraisal would cost more than the ring is worth -- The value of diamands vs size is logarithmic -- what you have is called an illusion setting ( bunch of small dimands put together to make it look like one larger diamond ) -- can also be done with just white gold surrounding a diamond -- I would say 30-60 bucks --- much better than a great day finding clad!! -- Keep up the good work.
