GIA 's graders grade it as SI quality that may not be shown the numerous of cloud on the cert, but it may affected its apperance and reflection . that's why they graded it as SI quality since I have been grading diamond for such long time in Carlsbad GIA lab center. it's better to see the actual stone instead of looking on the certificate. Don't challeage GIA cert nowaday because the certificate not signed by only ONE grader.
坦白講,世上那一種東西是保值呢?每樣野都有損耗的。好在鑽石就冇,但講到保值,咁就要買最好的,因市場真係越黎越少,我入行超過15年,由最初賣D color, IF , $100,000卡到而家超過$300,000一卡都有,你話幾誇張!當然,如果世界經濟或自己經濟差,咩都要賣啦,咩都唔保值啦!例如黃金一樣,80年頭我家姐結婚買$4xxx一両黃金,又升又跌,曾經200x年又跌到破80年代嘅價,而家又升到美金1700一安士,成$16-17000一両,唉!所以最緊要有鬆動錢買呢D心頭好!做呢一行,我都化Lu....
