Hi everyone. I have a quick question. My mom would like to get me a pair of diamond stud earrings as a wedding gift. I am currently interested in a 1.5tcw. The jeweler in the mall has one that is 1.5tcs G SI1 for $3999. I no very little about diamond studs. So I have no clue if this is a good price or not. I did a little research on Whiteflash and Bluenile to get an idea of how much it would cost for a pair with those specs and they all seem to be around that price range. Can I do better? Also, for diamond studs do the diamonds need to be certified?
