you know that opalescent pinky/white shimmer that you can get from all 3 of these pigments? is there a MAC shadow like that? i was thinking... i don't think there is. wouldn't that be so pretty!
ohhhh i am glad you asked this. I love the opalescent colors. I thought seedy pearl and crystal had something a little bit similar to pink opal, though they are more sheer than the pigments.
