Onyx amulet

The Onyx amulet is made by using an Onyx stone and a Gold bar on a Furnace with an Amulet mould in your inventory, or in your toolbelt. It requires a Crafting level of 90 and provides 165 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. It is noted that Grum's Gold Exchange in Port Sarim doesn't buy or sell Onyx/Dragonstone rings, necklaces, or amulets; the store only buys/sells jewellery made of Diamond or lower. The Onyx amulet can be enchanted into an Amulet of Fury by members through the use of the Enchant Level 6 Jewellery spell, or Onyx enchant tab made from a Lectern in a Player-owned house.

Trivia

 * The ball of wool used to make this amulet seems to be stained black in the making of this amulet
 * Despite having to use a gold bar to make an Onyx Amulet, there is no gold visible on the model of the amulet.
 * In Runescape 2 Beta Onyx was called "Black". So it would be "Black amulet" not "Onyx amulet".
