Trinket of fairies

High alchemy turns Trinket of fairies into 6,000 gp. Buying one at 67,049 gp (its guide price, as it has not traded today) and casting with a nature rune at 137 gp costs 67,186 gp. That is a loss of 61,186 gp per cast at its guide price, so it is not worth alching for profit right now.
