Quartz vs. Granite: What's the Difference?

Edited by Aimie Carlson || By Harlon Moss || Published on January 9, 2024
Quartz is a hard, crystalline mineral composed of silicon and oxygen, while granite is a coarse-grained igneous rock made of quartz, feldspar, and mica.

Key Differences

Quartz is a mineral consisting solely of silicon dioxide (SiO2), forming in various geological environments. Granite, in contrast, is a rock composed of quartz, feldspar, and other minerals, formed from cooled magma.
Quartz often appears as clear or translucent crystals, while granite has a granular texture with visible grains of quartz, feldspar, and mica.
Quartz is renowned for its hardness and resistance to scratching. Granite, while also durable and hard, is a mix of several minerals, affecting its overall strength and resistance to wear.
Quartz is used in making jewelry, glass, and as a component in various industrial processes. Granite is widely used in construction, notably for countertops, flooring, and as a building stone.
Quartz can be found in a variety of colors and forms, including amethyst and citrine. Granite offers a range of patterns and colors due to its composite nature, with each slab being unique.

Quartz and Granite Definitions


A widely occurring mineral used in jewelry and as a gemstone.
Her necklace had a beautiful rose quartz pendant.


A coarse-grained igneous rock composed mainly of quartz, mica, and feldspar.
The kitchen had countertops made of polished granite.


A material known for its durability and resistance to chemicals.
Quartz countertops are popular due to their durability.


A common and widely used building material known for its strength.
The old city hall was constructed entirely of granite.


A hard, crystalline mineral composed of silicon and oxygen.
The quartz crystal was transparent and perfectly formed.


A rock used for its aesthetic appeal in architectural applications.
Granite flooring added elegance to the hotel lobby.


A crystal used in electronic devices for its piezoelectric properties.
Quartz is essential in making accurate watches.


A rock used for monuments and memorials due to its durability.
The war memorial was carved from a single block of granite.


A very hard mineral composed of silica, SiO2, found worldwide in many different types of rocks, including sandstone and granite. Varieties of quartz include agate, chalcedony, chert, flint, opal, and rock crystal.


A material favored for its unique patterns in interior design.
Each granite slab had a distinctive pattern and color palette.


(mineral) The most abundant mineral on the earth's surface, of chemical composition silicon dioxide, SiO2. It occurs in a variety of forms, both crystalline and amorphous. Found in every environment.


A common, coarse-grained, light-colored, hard igneous rock consisting chiefly of quartz, orthoclase or microcline, and mica, used in monuments and for building.


Crystal meth: methamphetamine hydrochloride.


Unyielding endurance; steadfastness
A will of granite.


A form of silica, or silicon dioxide (SiO2), occurring in hexagonal crystals, which are commonly colorless and transparent, but sometimes also yellow, brown, purple, green, and of other colors; also in cryptocrystalline massive forms varying in color and degree of transparency, being sometimes opaque.


(rock) A group of igneous and plutonic rocks composed primarily of feldspar and quartz. Usually contains one or more dark minerals, which may be mica, pyroxene, or amphibole. Granite is quarried for building stone, road gravel, decorative stone, and tombstones. Common colors are gray, white, pink, and yellow-brown.


Colorless glass made of almost pure silica


Toughness; the quality of having a thick skin or being rough.


A hard glossy mineral consisting of silicon dioxide in crystal form; present in most rocks (especially sandstone and granite); yellow sand is quartz with iron oxide impurities


A crystalline, granular rock, consisting of quartz, feldspar, and mica, and usually of a whitish, grayish, or flesh-red color. It differs from gneiss in not having the mica in planes, and therefore in being destitute of a schistose structure.


A mineral occurring in different colors and varieties.
The museum displayed quartz in various colors, including amethyst and citrine.


Plutonic igneous rock having visibly crystalline texture; generally composed of feldspar and mica and quartz


Something having the quality of granite (unyielding firmness);
A man of granite
