Treat her like a Princess - Choosing a center stone that is anything other than a diamond is very popular amongst the ladies these days. (Thanks Diana and Kate!) Especially if it's a sapphire, emerald, ruby, or any other semiprecious gem. You can even add touches of smaller, more affordable diamonds around the larger rock. Mom knows best! - Get your future mother-in-law in on the action. No mom wants her baby girl to go without, so ask her if she has a special diamond or other gem she wouldn't mind parting with.
