Stone Mountain, though often called a pink granite dome, actually ranges in composition from quartz monzonite The minerals within the rock include quartz, plagioclase feldspar, microcline and muscovite, with smaller amounts of biotite and tourmaline.
The tourmaline is mostly black in color, and the majority of it exists as optically continuous skeletal crystals, but much larger, euhedral pegmatitic tourmaline crystals can also be found in the mountain's numerous, cross-cutting felsic dikes.
The summit of the mountain can be reached by a walk-up trail on the west side of the mountain or by the Skyride aerial tram.
