I remember this book I had when I was a child, it was a compilation of fairy folklore from all over the world. I think I bought the book at a book fair. I can only remember the beautiful illustrations and one story. The story was about a princess who was about to get married and fairies decided to bring her gifts, one went to the deepest part of the ocean and brought a sapphire, one went to a somewhere and brought her a ruby, and one went to somewhere else and got her a diamond. She couldn't decide which to wear and was very upset and so one fairy went to a volcano and dropped all 3 into it, making the first opal which the princess wore to her wedding... any thoughts on the book?
