I have a loose diamond that I want to get appraised prior to having it set and such. The main reason is that the place I am having it set has indicated that they will foot the bill should something happen during the process so I want to do a before/after appraisal to verify that no damage has occurred and if it has that they will be held accountable. I am very unfamiliar with the varieties of appraisals that can be done and would like input on what types I would need along with individuals/places who can do it.
