Where Does Quartz Come From?

Quartz is the most abundant and widespread mineral or mineralised form of silica dioxide to be more precise.

A component of many natural stones, quartz is also found in isolated crystals.

But where does it come from?

This versatile mineral crystallizes in intricate shapes that are colourless or endowed with colours and the deposits differ from one another. In fact, quartz crystals are so abundant in nature that the term “crystal”, which today designates a certain physical state of the matter in general, was once used solely to indicate quartz crystals.

Quartz crystals both vary in size and shape from microscopic deposits to macroscopic formations.

Hyaline crystals, which are colourless and transparent, are often inlaid in white Carrara marble to enhance the elegance of the stone.

Coloured crystals include varieties such as the Brazilian amethyst which is purple, yellow “false topaz” of Brazil and “ruby” of Bohemia, which has a blush pink shade.

Apart from these popular varieties, blackish, greenish, and red quartz crystal are also abundant in nature.

The colour is determined by the amount of iron oxide in the mineral and also by chemical reactions between iron, chlorites, and other substances. Produced by the slow crystallisation of silica hydrogels at a high temperature and pressure, quartz is either natural or man-made.

The natural mineral is often found in many volcanic stones such as granite, but also in quartzite, a metamorphic rock produced by geological processes from pure quartz sandstone.

Quartz In Interior Design

In its purest composition of crystals, transparent colourless quartz is used in the manufacture of luxurious decorative objects like lamps, vases, or statuettes.

Mixed with volcanic rocks, this mineral is often used for worktops and floorings. The highest concentration of quartz is found in granite, but marble also has quartz in its composition.

Quartz sandstone is often used in glass and ceramic industries, then transformed into design objects and home decorations.

But quartz sandstone or crushed quartz crystals are also the main component of engineered stone, one of the most popular worktops and flooring materials.

Made of 95% quartz and 5% synthetic resins, engineered stone is often referred to as “quartz” and the material is widely appreciated for its resistance and durability.

Quartzite, the metamorphic stone mentioned above, is used in the same way as engineered stone but comes with more advantages and fewer drawbacks.

Quartzite flooring and worktops are more resistant than quartz because the material is all natural.

Formed through extreme heat and pressure, quartzite doesn’t suffer burns or sunlight discolourations, it needs less maintenance and lasts longer than engineered stone. Moreover, quartzite is available in more or less the same colours as quartz and complements with success in all environments.

Cleaning either quartz or quartzite is easy with dish detergent and warm water.

Due to their unporous nature, neither quartz nor quartzite needs to be coated with a sealant, which is another great advantage.

Apart from these uses, quartz is also used in its crystal state as a decoration in residential and commercial contexts thanks to its natural fascination and unparalleled beauty.
