A Ruby ring is a useless item that can be made with the Crafting skill. Like all rings, it cannot be equipped in RuneScape Classic. It is made by using a gold bar on a furnace while having a ring mould and a ruby in the character's inventory. This requires a crafting level of 30 or higher and provides 70 crafting experience.
In Zanaris there is an NPC named Irksol who buys and sells Ruby rings.
A non-tradeable ruby ring is made in the Family Crestquest out of special fine gold.
