Unfortunately on of my friends is divorcing and has money troubles to go along with it and must sell her custom three stone engagement ring. She does not have a GIA report but her appraisal states that all three stones are VS1-G and it appraises out at 15K (the apprasal is years old) The center stone is 1.25 and the sides are .45. Should her first step be to get the stones GIA certified? Any advice is appreciated.
