by kenny » Jul 6, 2010 Both are untreated Kashmir Blue Sapphire from the same vendor. Stone 1: http://kashmirblue.com/Sapphire/Certs/profileLG10329.html is waiting for its GRS Certificate. Stone 2: http://kashmirblue.com/Sapphire/Certs/profileLG10351.html has its AGL report. Stone 1 vs. Stone 2: Weight 1.6 vs. 2.03 ct Depth% 90 vs. 76 Tone% 80 vs. 75-80 Average brilliance 75% vs. 80-100 Clarity MI2 vs. :LI2 Price $ 2,200 vs. 11,500 Clearly the second one should cost more . . but why is it over five times the price? Is AGL more reputable than GRS? What am I missing? Is the price mostly set by things not graded on the report?
