I am very new to this forum and there's a great deal of information. Most of the questions I googled led me to this forum and answered my questions. My real dilemma is I'm planning to get engage 2 months from now and I'm having a hard time deciding the size of diamond should I get. I am currently looking at a GIA .75 ct Round G-H in color VS2 in clarity excellent cut for about 3600-3800. But when I went to a jewelry store to see how they look its pretty amazing but the size compared to a 1.0 ct is quite huge. Now, I'm leaning towards 1.0 ct but my diamond budget is limited to 4k. Should I sacrifice quality over size? Can I still get a decent clean eye bright 1.0 ct diamond with my budget? Also, my girlfriend is 4'11, with a finger size of 5... Does .75 would look big enough on her finger? The jeweler said that you would only notice that .75 is small when there's a 1 ct beside it... lol. Thanks in advance. Really need anybodys opinion.
