by hoorray » Jan 24, 2004 I'm trying to decide what size / budget to look for in diamond studs. I've know the general range I want is somewhere from just under 1tcw to 1.4cttw, but most mall jewelers have just had those 2 increments, nothing inbetween. My question is when I look at the sizes in mm, how big of a difference will be visible -- especially since these will be earrings? ex. will 5.2mm look very different from 5.1 or 5.05? (I know this has come up before, but I couldn't find it when I did some searches.) Thanks for your help!
