Is there a trustworthy place in Philly that anyone would recommend getting a diamond engagment ring appraised at? I am concerned about diamond switching or other scams if i went to a smaller place. Any ideas? Also when i get it appraised i was going to ask for a SARIN and IdealScope to be done on it. Is this a reasonable request? How much would an appraisal like this run? Part of the reason i ask is to ensure i got a good value and also for an accurate appraisal to Jeweler''s Mutual.com . Thanks in advance for the help.
