I think you are right about white gold to suit a black pearl,Glitter Girl.I have had this pearl for ages,and think it`s time I did something with it-although it is classified as being `black` it has more of a charcoal lustre to it.
I generally like silver and white gold – it seems more delicate to me.
But most of my sentimental pieces are gold, so gold has that special feeling as well for me 🙂
