Gol is a city on the planet Vulcan.
The Stone of Gol likely takes its name from this city. (TNG: "Gambit, Part I", "Gambit, Part II")
In a Vulcan telling, the city is destroyed by an invading army after a citizen of Gol called Nirak mistakes their approach for a sandstorm. Henceforth "Nirak" became the Vulcan word for "fool". (ENT: "Kir'Shara")
