Buy OSRS Ruby amulet
The ruby amulet is a piece of gold jewellery in Old School RuneScape. It is a free to play item, so members and non-members can both use it. It is tradeable, equipable, noteable, and not stackable.
Players make a ruby amulet by using a gold bar on a furnace with a ruby and an amulet mould in their inventory. This needs level 50 Crafting and gives 85 Crafting experience. The amulet must be strung before a player can wear or enchant it. Stringing is done with a ball of wool or the String Jewellery spell, and it gives 4 Crafting experience.
The main reason players want a ruby amulet is to turn it into an amulet of strength. This is done with the Lvl-3 Enchant spell, which needs 5 fire runes, 1 cosmic rune, and level 49 Magic. The amulet of strength is a popular choice for melee combat.
A ruby amulet is also a solid pick for training Crafting. Cutting the ruby, making the amulet at a furnace, and stringing it gives a total of 174 Crafting experience. The item is light, so it is easy to carry in bulk.
