The Jade is designed to be a little more stable for players who loved the Diamond, but as their game grew they needed a disc that could handle a little more speed. The Jade sits very comfortably in the hand, with a good tactile feel to the plastic and it holds the angle well. You can turn it over but unless you really force it heavily, it seems to come back with a slight fade at the finish. A very nice, reliable, and moderately stable disc.
