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 dusty or cloudy quartz.{{wob ref|3203}}{{wob ref|295}} If a spren was trapped inside, they would be released.{{wob ref|292}}

 

If sung to, while holding Light, Polestones will break.{{book ref|sa4|86}}

 

All Lights can be stored in gems. How long a given quantity of Light will remain in a specific gem depends on the type of Light and the quality of the gem.{{book ref|sa4|16}} The rate at which a Light leaks from gemstones is not constant either - it appears slow at first, but accelerates rapidly near the end, making gems that begin to dim, dim ''fast.''{{book ref|sa4|32}} Regardless of the type of Light, perfect gems are said to be able to hold it indefinitely, but they are extremely rare.{{book ref|sa4|13}}

 

If a Polestone is set in the pommel of a deceased [[Shardblade]] it allows the blade to be bonded, whereby it can be summoned and dismissed.{{book ref|sa2|67}} Synthetic versions of the Polestones could also be used in fabrials.{{wob ref|2702}}
