Key Differences
Garnet encompasses a group of minerals with similar physical properties but differing in chemical composition, leading to a variety of colors and types. These minerals are commonly used in jewelry due to their luster and color diversity. Quartz, on the other hand, is a single mineral known for its durability and is found in many forms, including amethyst and citrine, making it versatile in both industrial applications and gemstone market.
Garnet is typically known for its deep red varieties, such as pyrope and almandine, which are highly sought after in the gemstone market. Quartz, whereas, offers a broader color range due to various impurities, including purple (amethyst), yellow (citrine), and clear (rock crystal).
In terms of hardness, garnets are generally hard (6.5 to 7.5 on the Mohs scale), making them durable enough for various jewelry settings. Quartz outmatches garnet slightly in this regard, with a hardness of 7 to 7.5, making it one of the most durable gemstones available.
From a metaphysical perspective, garnet is often associated with passion, energy, and health, making it a popular choice for those who believe in crystal healing. Quartz is attributed with amplifying energy and thought, as well as the effect of other crystals, making it a cornerstone in metaphysical practices.
Industrial applications differentiate them significantly; garnet is prized as an abrasive material due to its hardness and sharp edges, used in waterjet cutting and sandblasting. Quartz's piezoelectric properties make it invaluable in electronics and technology, including watches and oscillators.

Garnet
Garnets ( ) are a group of silicate minerals that have been used since the Bronze Age as gemstones and abrasives. All species of garnets possess similar physical properties and crystal forms, but differ in chemical composition.
Quartz
Quartz is a hard, crystalline mineral composed of silica (silicon dioxide). The atoms are linked in a continuous framework of SiO4 silicon-oxygen tetrahedra, with each oxygen being shared between two tetrahedra, giving an overall chemical formula of SiO2.
Garnet
Any of several common, widespread aluminum or calcium silicate minerals occurring in two internally isomorphic series, (Mg, Mn, Fe)3Al2Si3O12 and Ca3(Cr, Al, Fe)2Si3O12, generally crystallized, often embedded in igneous and metamorphic rocks, and colored red, brown, black, green, yellow, or white and used both as gemstones and as abrasives.
Quartz
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.
Garnet
A dark to very dark red.
Quartz
(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.
Garnet
(mineral) A hard transparent mineral that is often used as gemstones and abrasives.
Quartz
Crystal meth: methamphetamine hydrochloride.
Garnet
A dark red color, like that of the gemstone.
Quartz
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.
Garnet
Of a dark red colour.
Quartz
Colorless glass made of almost pure silica
Garnet
A mineral having many varieties differing in color and in their constituents, but with the same crystallization (isometric), and conforming to the same general chemical formula. The commonest color is red, the luster is vitreous, and the hardness greater than that of quartz. The dodecahedron and trapezohedron are the common forms.
Quartz
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
Garnet
A tackle for hoisting cargo in or out.
Garnet
Any of a group of hard glassy minerals (silicates of various metals) used as gemstones and as an abrasive
