FIRST diamond purchase and I could certainly use a few honest, expert opinions. Planning to fly my lady out to Italy, after an upcoming military mission, and pop the question. Looking for a ~3 ct. round. Must be VVS1, Color: D. Would like to stay under $3,000 if possible ,but could be convinced slightly more. I've used table/depth/L:W suggestions from forums to narrow down my search on LGD but still overwhelmed with the options. Im not particularly picky but she deserves nothing less than the best. Any suggestions would be greatly appreciated!
