Berserker icon

High alchemy turns Berserker icon into 4,800 gp. Buying one at 3,902,857 gp (its guide price, as it has not traded today) and casting with a nature rune at 138 gp costs 3,902,995 gp. That is a loss of 3,898,195 gp per cast at its guide price, so it is not worth alching for profit right now.
