My experience with jades is only black jades give necklaces and dragon wand
the white and red jades you can manufacture delicate red and white jades with; Don't know yet what they do
black and black give water necklace, red jade necklace, emerald necklace and with a little bit of luck you get dragon wand. No need to use alchemy books, if you don't get what is written above just compound random stuff till you get higher
