Spheres are made of small gemstones that are set inside glass spheres. The glass sphere is typically the size of a thumbnail while the size of the gemstone inside varies with the denomination.{{book ref|b|twok|c|3}} Most spheres are also flattened on one side, to keep them from rolling away when set down.{{book ref|b|twok|c|27}} Since gemstones can capture stormlight and glow with this captured light, spheres, by extension, also glow with light.

Only nine of the ten Polestones are used in the spheres,{{book ref|b|twok|c|8}} but it is as of yet unknown whether smokestones or heliodor are the gem not used, or the reason for the tenth gem's absence.

If left outside during a [[highstorm]], the gemstone inside of a sphere is infused with [[Stormlight]]. Over time, all of the Stormlight will escape leaving the sphere dun, so it ceases to glow.{{book ref|b|twok|c|44}} The amount of light a sphere gives off varies with the denomination: chips barely have any glow at all, marks glow almost as bright as a candle, and broams glow with the light of several candles.{{book ref|b|twok|c|3}}

Due to this property of gemstones, infused spheres are often used as a source of light, since the light is renewable and more consistent than candles and lanterns.{{book ref|b|twok|c|23}} Though the light given off by a gemstone is reputed to be steady and calm, this is only in comparison to the even more flickering candlelight; [[Kaladin]] observes that the Stormlight inside of a gemstone is actually shifting like a chaotic blowing storm.{{book ref|b|sa2|c|22}}

Although spheres are generally a superior source of light, many people, especially those less well-off or living in poorer districts, still use candles or lanterns. Using candles and lanterns is often cheaper than using spheres, since a sphere's dual status as currency makes it liable to be stolen. This problem does not exist for wealthy or noble [[lighteyes]] who may use all-sphere lighting either as a practical matter or to show off their wealth. For example, the entirety of [[Kharbranth]]'s royal treasury is stored in the [[Palanaeum]] to be used as a source of light for the visitors and staff.{{book ref|b|twok|c|33}}

Dun spheres are worth the same as infused ones{{book ref|b|twok|c|17}} but since their glow is what proves that they aren't counterfeit, people are often suspicious of those spending dun spheres. They will call in a moneylender to judge their authenticity.{{book ref|b|twok|c|3}} Instead of just leaving their spheres out in a highstorm, people often exchange their dun spheres with moneylenders for infused ones or pay a fee to have their spheres infused in the moneychanger's secure baskets.{{book ref|b|twok|c|11}}

There are five chips to a mark and four marks to a broam.{{17s ref|180|post|18839|Peter says five chips per mark, four marks per broam}} A higher denomination has a larger gemstone inside of it. However, the kind of gemstone set inside the sphere also determines the value of the sphere. This is related to the fact that magic such as [[Soulcasting]] uses gemstones in the process; emerald, the most highly valued sphere, can be used to Soulcast food.{{book ref|b|twok|c|3}} There are currently five known values of spheres (and by extension, five known gemstones used in spheres), with some combinations of denomination and gemstone overlapping in value.{{17s ref|180|post|18839|Peter says that some spheres are of equal value}}
