I am getting my 1.244ct AGS0 princess cut F SI1 diamond from whiteflash tomorrow. I will have it set next week with a jeweler in Springfield, MO. Should I have the loose diamond appraised while I am in St. Louis? If so, do you have any suggestions on a reputable appraiser in STL/ St. Charles area? Or should i wait until after I get the ring completely completed, then get it appraised? the reason I would get it appraised before-hand would be to make sure that I have the diamond that I payed for, and I want to be sure that I have the diamond that I payed for after it is set.
