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, 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.[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]
While polestones are produced via mining, a significant source of them on Roshar is the harvesting of the gemhearts that grow inside greatshells. Larger species of greathshell, like chasmfiends, produce gemhearts of great size, which are incredibly useful in Soulcasting as a larger stone is less likely to break from the strain.[5] This trait however has led to many species of greatshells, such as the lanceryn.[6] The exact method by which gemhearts are grown is not understood, though it is known to be caused by a leak from the Spiritual Realm into the Physical, and is analogous, though not identical, to the production of atium in the Pits of Hathsin on Scadrial.[7] Although they may have flaws, gemheart polestones have virtually no impurities, unlike their conventionally mined counterparts.[8]
It is believed to be impossible to create polestones via Soulcasting.[9]
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.[10]
The Ten Polestones
Sapphire
Sapphire is associated with the Essence of Zephyr. They are used to Soulcast translucent gases, like air.[11]
Sapphire spheres are given the "sky-" prefix.[12]
Smokestone
Smokestone is associated with the Essence of Vapor. They are used to Soulcast opaque gases, like smoke and fog.[11]
Smokestones are used in a type of fabrial clock.[13]
Ruby
Ruby is associated with the Essence of Spark. They are used to Soulcast fire.[11]
Rubies are used in the production of conjoiner fabrials, where a single infused ruby is split in two. Once activated the two halves will mirror each others movements, lift one and the other will also rise.[11] Spanreeds are a common application of this phenomenon.[14]
Rubies are also used in a kind of heat producing fabrial.[15] They are also used in the construction of a painrial, a pain reducing fabrial, designed by Longshadow and adapted by Navani Kholin.[16] A ruby was also part of the Oathgate at the center of the Shattered Plains.[17]
Ruby spheres are given the "fire-" prefix.[1]
Diamond
Diamond is associated with the Essence of Lucentia. They are used to Soulcast crystals, like quartz, and glass.[11]
Diamonds are used in a kind of light producing fabrial.[17]
Diamond spheres are given the "clear-" prefix.[18]
Emerald
Emerald is associated with the Essence of Pulp. They are used to Soulcast plant material, like wood and moss.[11]
Emeralds can be used to capture flamespren.[2]
Garnet
Garnet is associated with the Essence of Blood. They are used to Soulcast the eight types of blood and all other non-oil liquids.[11]
Garnets are used in a type of water attracting fabrial.[19]
Garnet spheres are given the "blood-" prefix.[20]
Zircon
Zircon is associated with the Essence of Tallow. They are used to Soulcast oils.[11]
Amethyst
Amethyst is associated with the Essence of Foil. They are used to Soulcast metals.[11]
Amethysts are used in the production of reverser fabrials, where a single infused amethyst is split in two. Once activated the two halves will inversely mirror each other's movements, lift one and the other will be lowered.[11]
Topaz
Topaz is associated with the Essence of Talus. They are used to Soulcast rock and stone.[11]
A topaz was observed as part of a fabrial replicating Regrowth, an application of the Surge of Progression.[21]
Heliodor
Heliodor is associated with the Essence of Sinew. They are used to Soulcast animal material, like meat and flesh.[11]
Heliodors are used in the production of alerter fabrials. These fabrials can be used to detect a variety of stimuli, such as people and emotions, and give notice to its user.[22]The larger the heliodor, and as a result the more Stormlight that can be infused in it, the wider the fabrial's range is.[11]
A heliodor was observed as part of a fabrial replicating Regrowth, an application of the Surge of Progression.[21]
