Unlike modern fabrials, the ancient [[Surge]] fabrials were created by persuading Radiant spren to manifest in the Physical Realm.{{book ref|sa4|9}}{{book ref|sa4|46}} Their functioning is also different: for example, [[Soulcaster]]s require a request for aid, which is unnecessary in modern fabrials.{{book ref|sa3|i|4}} However, they still do involve spren being bound to gemstones in some way - two large spren can be seen guarding and controlling the [[Oathgates]] in [[Shadesmar]].{{book ref|sa3|116}} So long as the gemstones are preserved and the spren are not compromised, any Surge fabrial can be recreated to operate just as it used to.{{book ref|sa3|117}} Any [[Surge]] can be replicated by fabrial science.{{wob ref|3013}} However, in the present day, fabrials that use Surges are extremely rare, and most of them date back to the era of the [[Knights Radiant]].{{cite}}

Once trapped in a gem, spren respond to stimuli in consistent and predictable ways. The metal frame surrounding the gem creates the stimuli the spren react to - pressing metal against a flamespren in a ruby increases and decreases heat.{{book ref|sa3|33}} Spren react to different metals in different ways, with their behavior generally paralleling the [[Allomantic]] powers for each individual metal,.{{epigraph ref|sa4|7}} though some metals that are not Allomantically viable still have effects on fabrials.{{wob ref|15138}} Multiple fabrial gems can be placed inside a single wireframe, which lets them work together to create more complex results. The [[emotion bracelet]], for example, has ten gems, with patterns in which they light up corresponding to different emotions.{{file ref|Navani2.jpg|text=Navani's Notebook: Two}} The [[God Metal]] which [[Shardblade]]s are composed of can be used in fabrials.{{wob ref|14138}}
