The thunderstone amulet is made by using a thunderstone and a gold bar on a furnace with an amulet mould in your inventory. It requires a Crafting level of 116 and provides 273 experience when made. The amulet must be strung before wearing by using a ball of wool or the String Jewellery spell (Lunar Magicks are required for this spell). Stringing provides 4 Crafting experience. The amulet may be enchanted into an amulet of destruction by players through the use of the Enchant Level 8 Jewellery spell. Most players who are lucky enough to obtain a thunderstone decide to turn their gem into a thunderstone amulet, since the amulet of destruction is the most sought after piece of jewellery.
