(→‎The Ten Polestones: Added associated orders to each polestone, according to their entry in the Wiki)
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.{{book ref|sa1|3}} 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 [[fabrial]]s.{{ref|name=Navani1}}
 
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]], despite being very similar chemically, are different metals in the [[Metallic Arts]], the exact color and chemical signatures are enough to differentiate the polestones. As a result, an off-color polestone acts much like an impure alloy in [[Allomancy]].{{wob ref|4080}} If a polestone was drained of its color by an [[Awakener]], it would still hold Stormlight but would have the properties of a colorless polestone.{{wob ref|3203}}
 
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 kind of substances a Soulcaster can transmute objects into.{{wob ref|2784}}
