by finnr » Jan 6, 2011 I just purchased a round brilliant loose diamond online and my next step is to pick out a setting and have it mounted. I did not want to get the setting online because there is a particular brand I like that is only sold in certain retail stores. My question is are most jewelers willing to sell someone a setting only and then mount the diamond that was purchased elsewhere into that setting? Or do some refuse or hesitate if you don't buy the diamond from them? Is there typically a mounting fee? I had looked at diamonds & settings in several stores but decided I could get more diamond for the money online. So now I will be looking to go back and shop for the setting. Is this common practice?
