Hello, my husband has graciously agreed to buy me diamond earrings for my 40 bday/having twins this year. I am thinking I want around 3-4 ctw and have a budget of around $25K. Any suggestions of where and what stones to buy? I like round and am intrigued by the ascher cut. I live near San Francisco and have access to the jewelry mart. Are internet prices as good? Thanks in advance to those who help! Anne
