So I''ve just been put up to a new task....my mother''s boyfriend has just informed me that he wants to buy my mother diamond stud earrings for Valentine''s Day. It''s kinda short notice but I think it can done; however, I need some info. I have been doing a lot of research on here regarding e-rings especially here on PS, but I need to know if the same rules apply to earrings(in terms of cut, color, clarity, size). His price range is $1200-$1500. I know that she wants round with the screw on back(that may actually have another name). They must also be set in white gold. What size do you think I can get for that budget that are of good quality. Any info that you can share will be greatly appreciated!!! Thanks!!!
