Diamond jewellery is created by a player with a Crafting level of at least 43, by using a furnace while a player has a gold bar and diamond in their inventory, along with the corresponding mould. This is the highest level jewellery non-members can craft and enchant. At current costs, diamond jewellery costs 1,639 coins to craft and 634 coins to enchant, or 474 coins if using an earth elemental staff.
The jewellery is purely cosmetic until it is enchanted using the Magic skill to cast the Enchant Level 4 Jewellery enchantment spell, which may imbue the item with stat bonuses and/or special functions, such as teleportation. The spell requires a Magic level of 57. Non-members cannot craft diamond bracelets, and can only enchant diamond amulets.
