I had a pair of 1.2 ct diamond studs and lost one recently and will be suing the insurance money to upgrade. Total budget is $6,000. My studs were I2, j color and I loved them. I want larger carat size but I also want them to sparkle. My local jeweler showed me a pair of K, SI2, one very good, one excellent cut, for just under $7k but I was so annoyed that he only showed me one pair and that it was over budget that I decided to take my search online. My engagement ring is "a cut above" from white flash but I don't think that quality is necessary for earrings. Help me decide where to start and what I can "sacrifice" to get a larger size that still has sparkle.
