Hi everyone! I am considering making a purchase with Alex Park. My concern is in case I receive it in person and need to return it (I don’t anticipate returning, it looks beautiful), has anyone returned something to Alex Park? Would my shipping back (with insurance for a $4700 piece) be outrageously expensive? I have read usps registered mail is the most cost effective and safe way to return diamonds, but I can’t find any pricing info online. Thanks in advance!
