Common Quartz Varieties
Amethyst:
Color and Formation: Known for its striking purple hue, amethyst gets its color from iron impurities and irradiation. It forms in volcanic rocks and hydrothermal veins (Rock Seeker) (The Gemstone Factory).
Uses: Amethyst is popular in jewelry and is also believed to have calming and healing properties.
Citrine:
Color and Formation: Citrine ranges from pale yellow to reddish-orange and often forms by heating amethyst or smoky quartz. Natural citrine is rare; most commercial citrine is heat-treated (Rock Seeker) (Geology In).
Uses: Citrine is valued for its bright color and is used in various jewelry pieces, often associated with wealth and prosperity.
Rose Quartz:
Color and Formation: Exhibiting a pink to rose-red color, rose quartz gets its color from trace amounts of titanium, iron, or manganese. It is commonly found in massive form rather than well-defined crystals (The Gemstone Factory) (Geology In).
Uses: Known as the stone of unconditional love, rose quartz is used in jewelry and decorative items, and is believed to promote emotional healing.
Smoky Quartz:
Color and Formation: This variety ranges from gray to brown and forms when quartz is exposed to natural radiation. Its color intensity varies depending on the level of radiation exposure (Geology In).
Uses: Smoky quartz is popular in jewelry and is thought to have grounding and protective properties.
Clear Quartz:
Color and Formation: Clear quartz, or rock crystal, is colorless and transparent. It forms in many geological environments, often in large, well-formed crystals (The Gemstone Factory).
Uses: Clear quartz is used in a variety of applications, from jewelry to technological devices due to its piezoelectric properties.
