Diamond amulet (u)

A diamond amulet (u) is the unstrung version of the regular diamond amulet. It is made by using a gold bar on a furnace, while having a cut diamond and an amulet mould in the inventory.

Level 70 Crafting is required to make one, and this grants 100 experience. When used with a ball of wool, it becomes a diamond amulet, giving 4 experience. After it is strung, it can be enchanted into an Amulet of power, which requires level 57 Magic and yields 67 experience.
