A friend has a very deep wedding band in gold, it is a plain gold band. We measured it and it is 3mm wide x 3mm deep, can you believe that? She wants to get a new engagement ring to go with it as her previous one looks nothing alongside it. What style of ring do you think. She was thinking a 3 stone but what style shoulder, height or do you think another type of diamond ring would look better? At the moment she is just considering this.
