The spell is learned by participating in cleaning samples until a Clean necklace is extracted from a sample. When brought to an expert, the expert will teach the player how to enchant ruby necklaces. After this, Ruby Necklaces are enchanted by using the Enchant Level 3 Jewellery which requires level 49 Magic.
