Onyx amulet

The Onyx amulet is made by using an Onyx stone and an Amulet mould on a Furnace. 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. The Assist System can also be used if the player assisting has a Magic level of 87 or higher. However, some users wear the Amulet for showing off how much wealth they have.

Players can make a profit by buying the amulet on the grand exchange, and enchanting it then re-selling, yielding around 0 coins per amulet, although it is extremely hard to buy this item for the Grand Exchange price. Onyx Amulets sell for 30-40m street price.

Trivia
The ball of wool used to make this amulet seems to be stained black in the making of this amulet.
