Quartz:
Quartz is a widely distributed mineral composed primarily of silicon dioxide (SiO₂).
It exists in many varieties, including amethyst, citrine, rose quartz, smoky quartz, and aventurine, which are often used as gemstones.
It is the most abundant mineral on the Earth's surface.
Quartz is significant in various industries due to its physical and chemical properties, making it a key component in igneous, metamorphic, and sedimentary rocks.
Quartz has a typical crystal form of six-sided prismatic crystals with pointed terminations.
Additionally, quartz has been utilised since antiquity for jewelry and hardstone carvings, highlighting its historical and cultural importance. Its versatility extends to technological applications, making it one of Earth's most important minerals.
Quartz is a hard mineral composed of silica (silicon dioxide).
Its atoms are linked in a continuous framework of SiO4 silicon–oxygen tetrahedra, with each oxygen atom being shared between two tetrahedra, giving an overall chemical formula of SiO2. Therefore, quartz is classified structurally as a framework silicate mineral and compositionally as an oxide mineral. Quartz is the second most common mineral or mineral group in Earth's lithosphere, comprising about 12% by mass.
Quartz exists in two forms, the normal α-quartz and the high-temperature β-quartz, both of which are chiral. The transformation from α-quartz to β-quartz takes place abruptly at 573 °C (846 K; 1,063 °F).
Since the transformation is accompanied by a significant change in volume, it can easily induce micro fracturing of ceramics or rocks passing through this temperature threshold.
Quartz Gem Varieties:
There are many different varieties of quartz, several of which are classified as gemstones. Since antiquity, varieties of quartz have been the most commonly used minerals in the making of jewelry and hardstone carvings, especially in Europe and Asia.
Clear, colourless crystals are called rock crystals. The opacity of milky quartz is caused by iron hydrates in yellow citrine, ferric oxide in violet
Brown or smoky quartz, found, as huge crystals in Brazil, can be artificially produced by irfradiating rock crystals.
Quartz cat's eye, tiger's eye and hawk's eye have inclusions giving a wavy, striped effect.
Rutilated Quartz contains rutile needles intersecting at 60 degrees angles.
Minute reflective scales in aventurine quartz give a green or brown spangled appearance. Many varieties are used in jewellery and specimens of Amethyst are widely collected.
