Onyx ring
From Emps-World Wiki
An Onyx ring is made by using a Gold bar on a furnace whilst also having a Ring mould and an Onyx in the inventory. Doing so requires a Crafting level of 67 and gives 460 experience when made.
The onyx ring can be enchanted into a Ring of stone by using lvl-6 enchant from the Normal spellbook on it.
