Diamond bolts are adamant bolts tipped with diamond bolt tips. Diamond bolts can be created through the Fletching skill. A player must first have a Fletching level of 65 and take a cut diamond and use a chisel with it to make 12 diamond bolt tips. Attaching diamond bolt tips also requires a Fletching level of 65 and grants 7 Fletching experience per tip attached. Once the diamond bolt tips have been attached, the adamant bolts become diamond bolts.
