Hi Sam,

If inside the GIA report, there is no marking of H&A, is it represent that GIA do not agree it is 8 heart 8 arrow? If cut grade is just Very Good, is it mean that it must not be H&A? Thanks for your kindly advice.

And for below 4 diamonds, I am not sure which one is better and worth of money. Would you mind kindly advice how should I compare them? Thanks so much for your help!!!

HI,

GIA 評級是沒有八心八箭系統,H、A是鑽石加工廠自己評估,
所以沒有H、A 不一定沒有八心八箭,而cut grade是VERY GOOD是有可能有H/A,
因此每粒鑽石都要自己觀看八心八箭圖案,這是非常簡單,只要用小儀器就能夠檢測.
你給我的選擇,我會先選CUT GRADE 是EXCELLENT這粒鑽石,但他是IGI CERT
價格是貴了些少.
