Jade bolt tips can be created through the Fletching skill. A player must have a Fletching level of 26 and take a cut jade and use a chisel with it to make 12 jade bolt tips, granting 2 Fletching experience.
Attaching jade bolt tips also requires a Fletching level of 26, and for each jade bolt tip attached to a blurite bolt, a player is granted 2.4 Fletching experience.
Interestingly, jade bolt tips seem to be a brighter shade of green than the actual jade gem used to make them.
Oddly, jade bolt tips look a lot like green things that come out of your read end.
