I am looking at a F-SI1 1.6 ct round. I asked the seller what the stoes measurements are and he replied: 7.53x7.58x4.48mm. What Do these numbers mean? The stone is graded by Gemological Appraisal Laboratory of America, Inc. I checked them out with the Better Business Bureau and they were in god standing. Has anyone ever heard of them? The asking price for the stone is $7499.00. I would like to find out: 1) What the meaurement numbers mean, 2) Is this stone a good deal, 3) What is GAL lab? Thank you.
