Opal jewellery is created by a player with a Crafting level of at least 13, by using a furnace while a player has a silver bar and an opal in their inventory, along with the corresponding mould. At current costs, Opal jewellery costs 571 coins to craft and 512 coins to enchant, or 416 coins if using an air elemental staff.

The jewellery is purely cosmetic until it is enchanted with Lvl-1 Enchant, which may imbue the item with stat bonuses and/or special functions, such as teleportation. The spell requires a Magic level of 7.
