My wife loves jewelery so I have a custom jeweler who makes all my jewlery. He works out of his home which is to put it kindly a dump. He is probably 150# over weight, is covered in tatoos and wears a pony tail and full scraggly beard.
All that aside, he makes great jewelery to my specifications for probably 20% of retail. I just had him make a 5ct natural ruby center stone ring surrounded by 2 cts of alternating diamond and rubys for $350.
One of these trinkets and a trip to somewhere that our kids can't find us (Yousemite this year, Vegas and Santa Catalina Island other years - doesn't need to be expensive) is all it takes to score big points.
Point is, find out what she likes and do ALL the arrangements yourself and she will be very happy.
