Dream Amethyst (Chevron Amethyst)
Quartz variety Amethyst and Milky Quartz · Semi-Precious Gemstone / Mineral Specimen
Crystal System
Trigonal crystal system; typically occurs in massive or macrocrystalline habits with distinctive V-shaped (chevron) growth bands
Mineral Group
Silicates (Tectosilicate)
Chemical Formula
SiO2 (Silicon Dioxide) with color resulting from Fe3+ (iron) impurities and natural irradiation
Formation Process
Hydrothermal formation where silica-rich fluids crystallize in fissures. The 'chevron' patterns form from alternating layers of amethyst and milky quartz during varying stages of growth and temp changes
About This Crystal
A polished tumbled stone exhibiting a combination of deep purple amethyst and opaque white 'milky' quartz. It features a distinctive banded or V-shaped 'chevron' pattern with a vitreous to waxy luster and translucent to opaque sections
Physical Characteristics
Purple and white body color; white streak; no visible cleavage; conchoidal fracture; specific gravity 2.65; non-magnetic; may show weak fluorescence under UV light
Optical Properties
Refractive Index of 1.544-1.553; uniaxial positive; weak pleochroism in purple areas; doubly refractive; no notable dispersion or play of color
Hardness & Durability
Origin Region
Prominently sourced from Brazil, South Africa, Russia, and India, occurring primarily in hydrothermal veins and volcanic cavities
Hardness & Durability
Mohs hardness of 7; high durability and resistance to scratching; good stability for jewelry, though brittleness can lead to chipping under high impact
Care & Maintenance
Clean with warm soapy water and a soft brush; avoid steam cleaning or ultrasonic cleaners; keep away from prolonged direct sunlight to prevent color fading
