A runescape gold amulet is made by using a gold bar on a furnace with an amulet mould in the inventory. It requires a crafting level of 8, and gives 30 experience, making an unstrung gold amulet. The amulet must then be strung before wearing by using either a ball of wool or the String Jewellery spell. Stringing provides 4 crafting experience, and costs 182 coins if you buy the balls of wool.
There is currently a glitch where the gold amulet, when worn, appears green rather than gold, similar to the amulet of power glitch. This also happens with a gold amulet(unstrung).
A plain rs gold amulet cannot be enchanted; only jewellery with gems can be enchanted. Gems cannot be added to a gold amulet, because they must be added during the crafting process.
