I have started my hunt for a beautiful anniversary rings for my beloved wife of 20 years. I have set the budget around $4500 but willing to go up to $5500 and eat peanut butter and jelly for dinner for a few months. I have found many rings in my budget but I am having a hard time choosing. I want to get her the biggest diamond my budget allows without sacrificing sparkle. I have chosen Platinum as the setting, and the cut being the most important factor, I have decided to get excellent/ideal cut. My question is should I go with SI clarity and I-color and go for the biggest I can afford OR go with VS2 and H color, all other being equal? Which would give the biggest impact for the naked human eye. There in no doubt she would choose the one that would give the most wow factor. I am not interested in any quality that only shows up under magnification. I just want an eye-clean, biggest and one that gives the most sparkle within my budget. I am looking for at least .9 carat for the center but I am clueless on what to choose for the sides. I am open to any suggestion. Thank you much for your help.
