In jewelry, what kind of stone would you prefer?

What color, shape and size? Sparkling or simply the color like coral or Turquoise?

Amethyst is my birthstone or sapphire. I really do not see what the big problem is with diamonds – that see through! Does anyone know pulishing something about books? Help! If you can, please answer my question: http://answers.yahoo.com/question/index?qid=20090810005800AAR6rlD
