Emerald ring
From Emps-World Wiki
An Emerald ring is made by using a Gold bar on a furnace whilst also having a Ring mould and an Emerald in the inventory. Doing so requires a Crafting level of 27 and gives 220 experience when made.
The emerald ring can be enchanted into a Ring of duelling by using lvl-2 enchant from the Normal spellbook on it.
