Hi, I''m thinking of buying a diamond on line with very good to ideal cut that is in the 1.30 to 1.45 ct range that has at least 7.2mm diameter with G-H color and S1-S2 eye clean clarity. My price range is 6000 to 7000. It doesn''t have to be H&A as long as it''s ideal cut and sparkles like mad. Thanks in advance for your help! Also, if I decided on the stone from the online vendor, can I send my own ring mounting to them to have it set with the diamond?
