Kyanite is a blue to light-green, triclinic mineral that occurs in long, thin-bladed crystals and crystalline aggregates in gneiss, schist, and pegmatites. Andalusite is a yellow, brown, green, or red orthorhombic mineral that occurs in thick, almost green prisms in schist, gneiss, and hornfels.

The beach sand was deposited on top of the eroded-off surface of the Precambrian gneiss (seen at Stop #1A). Subsequent deformation during the building of the Appalachian Mountains metamorphosed these quartz sands to the very resistant quartz rock, called a quartzite, and tilted the beds from their original horizontal position.

CNC milling is a substractive fabrication method that uses computer numerical controls systems for automating the process. Milling Process. We could limit ourselves to describing the fabrication process only but giving an overview of the complete flow gives a more wholesome picture.
That's a Gneiss Stone! - Use Natural Stone
The parent rock of gneiss can be granite, but it can also be shale or an impure sandstone (meaning it contains more than just pure quartz sand). Previous articles have described the continuum of metamorphism as a stone is exposed to increasingly torturous heating and compression. Shale becomes slate, then phyllite, then schist, then gneiss ...

Metamorphic Rock Types: Pictures and Descriptions
Gneiss ("nice") is a rock of great variety with large mineral grains arranged in wide bands. It means a type of rock texture, not a composition. This type of metamorphic was created by regional metamorphism, in which a sedimentary or igneous rock has been deeply buried and subjected to high temperatures and pressures.
