The Diamond is the fourth tier out of 6 available gems. It is also the last tier to upgrade tools with.

A player will at least need 15 Diamonds to upgrade tools and complete quests with. Note that the Knight requires a Diamond Chisel, so it's not counted towards that amount. Tools have to be upgraded with a Ruby first.
