A mirror is typically considered nonmetallic because it is made from a layer of glass with a reflective metal coating on one side. The reflective coating gives the appearance of a metallic surface, but the mirror as a whole is not a solid metal.
There are three common types of nonmetallic luster: vitreous (glassy), pearly, and resinous. These types describe the appearance of a mineral's surface when light is reflected off of it.
The mineral that is nonmetallic and has a silky luster is serpentine. Serpentine is a group of minerals that are typically green in color and have a silky or waxy sheen on its surface. It is commonly found in metamorphic rocks.
