Starborn diamond

A starborn diamond can be found when Mining or on the Squeal of Fortune from 26 April 2013 to 6 May 2013. With one, it is possible to make Starfire weaponry into Starfury weaponry, which provides 250 Mining Experience per weapon. Starborn diamonds can be exchanged for 2,000 Mining experience per diamond by speaking with Ivar. It is currently not tradeable and is very rare to find while mining.
