| World of Origin | Roshar |
The Polestones are the ten varieties of gemstone that naturally hold Stormlight. They also serve as the basis of spheres, the basic Rosharan money system.[1]
In addition to the ability to hold Stormlight, polestones are able to trap spren. The type of spren that can be trapped depends on the polestone used and its cut. This quality serves as the basis for fabrials.[2]

Some polestones are the same type of crystal but with different color and chemical signatures. Sapphire and Ruby are both types of corundum. Smokestone and Amethyst are both types of quartz. Emerald and Heliodor are both types of beryl. Much like how iron and steel are different metals in the Metallic Arts, the exact color and chemical signatures are the determining factor. As a result an off-color polestone acts much like an impure alloy in Allomancy.[3]
Although the type of polestone Stormlight is stored in is irrelevant for most Surgebinding, polestones do have an important impact on Soulcasting. Namely they determine what objects can be Soulcast into.[4]
