I am in my late 20s and have been with my girlfriend for over 5 years and it''s about that time. Friends are starting to get engaged and the pressure is on! She has expensive taste and deserves only the best. That being said I have stepped up my budget beyond what any rational mind would advise. I already have a setting in mind that I love and plan to have custom made. As of today, my thoughts include a budget of around $30-35K, give or take a little, for the stone itself. I have decided that I want a stone of at least 3 carats with an ideal cut and was wondering whether to go for an H VS2 or H SI1 or a G SI1. I know that it all depends on the stone itself and have been told that some SI1 look nicer than certain VS2. Any help would be greatly appreciated!
