Onyx jewellery

Onyx jewellery is created by a member with a Crafting level of at least 67, by using a furnace while a player has a gold bar and onyx in their inventory, along with the corresponding mould. At current costs, onyx jewellery costs coins to craft and  coins to enchant, or  coins if using a lava elemental staff.

The jewellery is purely cosmetic until it is enchanted using the Magic skill to cast the Enchant Level 6 Jewellery enchantment spell, which may imbue the item with stat bonuses and/or special functions, such as teleportation. A Magic level of 68 is required to cast the spell. Non-members cannot craft onyx jewellery, nor can they enchant onyx jewellery.

Types
Note: Onyx amulets are crafted as unstrung amulets, and must be strung with a ball of wool before they can be worn or enchanted. The in-game name of both strung and unstrung versions is simply "onyx amulet".

Onyx ring (i)
In the Mobilising Armies minigame, a player may exchange an onyx ring and 144,100 reward points for a onyx ring (i), which provides stat bonuses. This ring is not tradeable.

Amulet of fury (t)
A trimmed version of the amulet of glory, the amulet of glory (t), is available to be purchased, traded, or earned from hard Treasure Trails. It cannot be crafted by players, and gives slightly better stat bonuses than its untrimmed counter-part.

Amulet of fury (or)
An amulet of fury that has had a Fury ornament kit used on it becomes an Amulet of fury (or). It is not tradeable in this form, however the kit and amulet of fury can be separated. The amulet is functionally equivalent to the standard amulet of fury.

Blood amulet of fury
An amulet of fury becomes a blood amulet of fury when combined with a blood necklace shard. The two cannot be separated, and the amulet cannot be traded in this form. This amulet offers the same stat bonuses, but also deals 400-600 damage to targets every 15 seconds, and heals the wearer by the same amount. This item degrades after 20 hours of combat, but is rechargeable.
