The color of Madirus quartzite ranges from light yellow to orange and red, and its color changes are rich and colorful. Its composition is mainly quartz, which has high transparency and luster. Structurally, Madirus quartzite has an obvious metamorphic structure, in which the metaphenocrysts are sodium-rich feldspars, and the matrix is composed of quartz and feldspar.
The morphological characteristics of Madirus quartzite are also very unique. Its cross-section is usually irregular and sometimes exhibits unique textures and cracks. These textures and cracks make each piece of Madirus quartzite unique and highly collectible. In addition, some small spots appear in some Madirus quartzites. These spots are caused by iron elements, adding a unique color to the rock.
Madirus Quartzite also excels when it comes to hardness, density and durability. Its hardness is high, second only to diamond, reaching 7 degrees on Mohs hardness scale. Its density is also larger, reaching 2.65 grams/cubic centimeter. In addition, because its composition is mainly quartz, it has good durability and can be stored for a long time without being easily damaged.
