Matrix adds weight and an opaqueness to the overall appearance of a quartz specimen. Sometimes matrix actually may add value if it allows the specimen to sit nicely without having to use a stand. If there is no matrix present, does the back appear to have been broken naturally or has it been broken by the miner from the host rock?
Quartzite Quartzite is a metamorphic rock formed when quartz-rich sandstone or chert has been exposed to high temperatures and pressures. Such conditions fuse the quartz grains together forming a dense, hard, equigranular rock. The name quartzite implies not only a high degree of induration (hardness), but also a high quartz content.
Quartzite is a metamorphic rock, while quartz is an igneous rock that crystallizes from magma or precipiates around hydrothermal vents. Sandstone under pressure becomes quartz arenite and quartzite, but quartzite does not become quartz. The construction industry further …

Apr 13, 2018· Quartz is an old German word that originally meant something like hard or tough.It is the most common mineral in the continental crust, and the one with the simplest chemical formula: silicon dioxide or SiO 2. Quartz is so common in crustal rocks that it's more notable when quartz is missing than when it's present.
Quartz can be classified as a crystalline rock whereas quartzite can be classified as metamorphic. Quartzite is widely used in the construction industry as slabs, roofing and flooring tiles and as crushed stones. Quartz has its application as a gemstone and it is also used in electronics.
What Are Some of the Uses of Quartzite? The most common use of quartzite is for dimensional stones in the construction industry. While construction also uses quartzite as crushed stone, this use accounts for less than 6 percent of the common uses for this type of material in the United States.
Rose Quartz is a massive form of Quartz, pale to deep reddish-pink, opaque to translucent; a "stone of beauty and love," it promotes compassion, appreciation and soothing calm. Prase is a leek-green Quartzite (rock rather than a mineral) with actinolite inclusions; an "earth mother" stone, it resolve conflicts and calms nerves.
By definition, quartzite is a light-colored, hard metamorphic rock, which forms from the metamorphism of quartz sandstone. When a rock - in this case quartz sandstone - is exposed to changing ...
Understanding Quartz and Quartzite. Quartzite is a naturally occurring metamorphic rock. It is created when sandstone is subjected to extreme heat and pressure caused by tectonic plate compression in the crust of the earth.
