What is Quartz?

Quartz is a group of minerals that can be found in igneous rocks such as granite and sedimentary rocks like sandstone and shale. They’re formed as a result of magma cooling down slowly which is vital for the crystallization. The main components in these crystals is silicon and oxygen which makes up the compound silicon dioxide. There are some other impurities in this gemstone such as lithium and titanium which result in specimens like Amethyst, Smoky Quartz, Citrine, Rose Quartz and much more. Numerous crystals like Agates and Jasper crystals also contain a network of Quartz. 

Quartz is a silicon dioxide mineral. It’s particularly hard with a 7 on the Mohs scale. This crystal is also durable in high temperatures. The fracture is conchoidal when the mineral breaks. 

Quartz’s name comes from the Polish word “kwardy” which means hard. This resembles the significant hardness of the stone.

 

Types Of Quartz

Quartz is one of the most abundant minerals on earth and comes in a wide variety of forms. From clear rock crystals to the deep purples of amethyst, this gem has the power to dazzle throughout the spectrum of the rainbow. Other varieties, such as milky quartz or the charming strawberry quartz, add further diversity to the quartz family. Other crystals like calcite and apophyllite can even be mistaken for quartz, so read on to learn the difference between quartz and other crystals, and how to identify types of quartz!

 

What does Quartz look like?

Quartz, arguably the most well-known crystal, is a crystalline mineral that ranges from from a transparent clear coloring to a solid milky white. Quartz can looks and feel like glass because of its nearly see-through appearance and incredibly smooth, almost flawless sides. They can often have internal cracks that cause rainbows or many other types of inclusions of other minerals.

Quartz is the most common mineral in the continental crust and is present in almost every rock and all three types (sedimentary, igneous, and metamorphic).

This mineral is so common that beach sand comprises large amounts of quartz; the whiter the sand, the higher the quartz content.

Quartz has a notable hexagonal structure of six flat sides and comes to either one point or can be pointed at both ends (it looks similar to a pencil). Quartz is most commonly found in “wands,” clusters, geodes, and as particles within other rocks.

Because it is so common, it can often have a wide variety of looks especially due to inclusions of other minerals and can take on nearly every shade from grays, to pinks, to yellows, to black and everything in between.

Despite the fact that quartz is one of the most common minerals found, it has been knocked-off as both lab grown and glass imitations.  If it looks TOO perfect, like perfect points, perfect cluster formation as a 360, etc., or if there are tiny little bubbles (not to be confused with natural enhydro bubbles), it is likely fake. But this is nothing new, the first ‘home grown’ quartz was in the 1840’s haha. Still be careful.

Learn more about the quartz family of crystals, including how to differentiate between the stones on the blog post dedicated to that.

Difference Between Clear Quartz & White Quartz

Clear Quartz and White Quartz, both belonging to the vast family of quartz crystals, share some similarities but also exhibit distinct differences. The most apparent distinction lies in their color and clarity. 

 

Difference Between Quartz and Citrine

Citrine is a captivating quartz variety that ranges in color from pale yellow to a translucent brown. The color of citrine may vary depending on the density of submicroscopic iron particles within the silicon dioxide. Natural citrine is quite rare, so ensure you're purchasing a natural stone rather than one altered by heat treatments, which often leave visible fine lines in the crystal.

Occasionally, citrine with hues of amber or orange forms due to specific geological conditions, and Amethyst and Citrine can sometimes occur together in the same crystal. This unique combination of citrine and amethyst produces the stunning gemstone known as Amethyst citrine or ametrine.

Difference Between Quartz and Smoky Quartz

Smoky quartz is a quartz variety with an alluring smoky effect caused by natural radiation interacting with aluminum impurities. Its colors range from transparent grays to opaque browns and blacks, offering a rich variety within its class of stone. Unlike quartz, smoky topaz—sometimes mistakenly marketed as such—belongs to a different gem family.

Difference Between Quartz and Rose Quartz

Rose quartz stands out with its delicate pink to deep rose-red hues. This variety gains its color from iron, manganese, or titanium impurities. Rose quartz typically forms in a cryptocrystalline form rather than clusters, setting it apart from other quartz types.

The actual stone color in rare rose quartz specimens may include deeper hues due to elements like aluminum or phosphate, making them more valuable.

 

Difference Between Quartz and Amethyst

Amethyst, a favorite purple gemstone, owes its vibrant hues to iron impurities exposed to natural gamma radiation. The resulting colors vary from bright violet to muted lavender. In some cases, carnelian onyx heliotrope shades may appear in amethyst due to trace impurities, adding to its charm.

Amethyst may also display color zoning, with more intense hues where iron impurities are denser. The occasional pairing of Amethyst and Citrine results in ametrine, a striking gemstone blending yellow and purple tones.

Difference Between Quartz and Chalcedony

Chalcedony, a cryptocrystalline form of quartz, exhibits beautiful opaque textures and bands. It includes varieties like green chalcedony, brownish chalcedony, and agate carnelian, showcasing the diversity of quartz’s hidden crystalline structures.

This variety is prized for its durability, making it a preferred material for cameo gems rock crystal and custom jewelry. Chalcedony’s banding, often found in Colorful agate or Scenic agates, adds visual appeal and uniqueness to each piece.

 

Difference Between Quartz and Calcite

This is the first stone on our list that doesn’t belong to the quartz family. We include it here because it is often confused for quartz although it is fundamentally different and resembles it only superficially.

Calcite is composed of calcium carbonate, more specifically CaCo3, or one calcium to three carbon atoms. Unlike the hexagonal shape of quartz, it forms into scalohedrons, rhombohedrons, and a variety of other shapes.

Calcite in its purest form is transparent, just like clear quartz. As a result of impurities, it can also be found in white, black, red, brown, yellow, orange, gray, and even occasionally, in blue varieties.

Where quartz is one of the harder minerals at 7 on the Mohs scale, calcite is much softer, coming in at 3. While the resemblance to quartz may in some cases be quite remarkable, the similarity is superficial.

 

Difference Between Quartz and Apophyllite

This is another stone that can be easily confused with quartz, although, like calcite, it belongs to an entirely different family.

Typically transparent, its chemical composition is potassium calcium silicate and it forms into wonderful cubic and pyramidal structures.

The name apophyllite comes from the Greek term ‘apophyllos’ which means ‘to flake off in leaves’. This describes its property of peeling apart under exposure to heat  which causes it to lose its natural water content.

This fascinating stone comes in white, pink, yellow, brown, violet, green, and transparent varieties. It may also be opaque under some circumstances. The most common type is transparent, leading to confusion with clear quartz.

Whether you’re a crystal newbie or a seasoned fanatic, Quartz is a great crystal for any collection! 

Now that you know the difference between the main types of quartz crystal, you can hopefully shop for crystals with more confidence!

Additionally, China offers a diverse range of quartz types, showcasing a spectrum of colors and characteristics. These include beautiful specimens like citrine, smoky quartz, and amethyst. Other countries such as Japan and South Africa also contribute to the global quartz supply, each with its unique selection of quartz varieties.

How Is Quartz Formed? (Scientific Breakdown)

Quartz is composed mainly of silicon dioxide, and in its purest form, it will form into a clear hexagonal crystal with pyramidal ends. Other elements such as inclusions, mineral impurities, heat, and natural irradiation from the surrounding rocks will add features and color to individual crystals, giving us many wonderful varieties, from the milky whites of vein quartz to the golden yellows of citrine, and many other types of quartz crystals.

When a silicon atom combines with two oxygen atoms, they form a single molecule of silicon dioxide, the chemical formula of quartz. The crystals then form into the distinctive hexagonal shape and tend to be mostly transparent, with a Mohs mineral hardness rating of 7. This makes it a relatively hard gem and quite suitable for jewelry as it is quite resistant to impact and other types of wear and tear.

Where there are impurities in the crystal due to geological conditions, the color of the stone may alter, giving rise to variants such as rose quartz, amethyst, citrine, Quartz Moss, chalcedony, smoky quartz, and others.

Quartz crystals can generally be divided into either macrocrystalline or cryptocrystalline. Macrocrystalline gems, such as amethyst, contain crystals that are easily visible to the naked eye, while cryptocrystallines, such as chalcedony, require magnification to see the crystals.

Of course, you also have other crystals and minerals that can grow WITHIN the quartz family of crystals, giving them inclusions like lodolite garden quartz, cacoxenite in amethyst, hematite or iron in quartz, Quartz One, rutile in smoky quartz, and many, many more.
