Hi! I've been reading posts for a couple of days, and it seems like everyone here knows a lot! I've been married for three years and have had a ring with a very small stone (.25 carat). We want to upgrade, but we don't have a lot. We can spend around $3000 for both the diamond and the ring. I've seen some stones that are around a carat for around $2000(like this one: http://www.jamesallen.com/diamonds/J-VS2-Premium-Cut-Asscher-Diamond-1137091.asp), but I don't understand some stuff, like what the cm measurements mean. Also, what's the lowest one can go on color before it's obviously not white? Is it preferable to have a stone that's inferior in color, or one that's inferior in clarity? I think I have my heart set on an Asscher cut, but I wouldn't mind something else if there's a shape that would look a lot bigger for the same weight. Things that are important are: price (under $3000), weight (around a carat). So many questions and so little money! Please tell us what to do!
