Jade bolt tips can be created through the Fletching skill. A player must have a fletching level of 26, a cut jade, and a chisel (in tool belt or inventory). Each jade makes 12 jade bolt tips and grants 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.
