Jadeite is mined in Burma. It wasn't introduced into China until 1750. Before that, all examples of Chinese jade were the mineral nephrite. Jadeite occurs in a wide range of colors, textures and translucencies. One could spend a lifetime studying jade and still not scratch the surface of what there is to learn.
