Rutile Quartz
Quartz var. Rutilated Quartz · Semi-Precious Gemstone
Crystal System
Trigonal system, typically forming as prismatic crystals with hexagonal cross-sections; fashioned here as polished spherical beads.
Mineral Group
Silicates (Subgroup: Tectosilicates)
Chemical Formula
SiO2 with inclusions of TiO2
Formation Process
Hydrothermal and igneous processes where needle-like rutile crystals (titanium dioxide) become trapped and encased within growing quartz crystals under high pressure and temperature conditions.
About This Crystal
The bracelet consists of polished, spherical beads displaying a translucent to transparent body with brownish-golden to dark brown hues. Internal needle-like and fibrous inclusions of rutile are visible, creating rich visual textures and patterns within the quartz matrix.
Physical Characteristics
Color ranges from clear/amber to dark brown with golden inclusions. Streak is white. Conchoidal fracture, no distinct cleavage. Specific gravity is approximately 2.65. Tenacity is brittle. Vitreous to sub-adamantine luster on polished surfaces.
Optical Properties
Uniaxial positive with a refractive index of 1.544-1.553 and low birefringence of 0.009. Shows doubly refractive properties. The inclusions create striking visual depth and scattering effects.
Hardness & Durability
Origin Region
Found globally with notable deposits in Brazil, Madagascar, Australia, India, and the United States. Forms within hydrothermal veins and pegmatites.
Hardness & Durability
Mohs hardness of 7 for the host quartz matrix, making it durable for daily wear as jewelry, though some surface-reaching rutile inclusions may be slightly softer.
Care & Maintenance
Clean with warm soapy water and a soft brush. Avoid harsh chemicals, ultrasonic cleaners, and prolonged direct sunlight to prevent any potential fading of specific color variants.
Rarity & Value
Moderately common to uncommon, with value heavily dependent on the density, clarity, and aesthetic arrangement of the golden rutile needles within the transparent quartz. Price ranges from affordable to moderate.
Special Characteristics
Features dense internal needle-like inclusions of rutile (titanium dioxide), often referred to poetically as 'Venus hair stone' or 'Cupid's darts', which provide striking visual patterns.
Lore & History
Historically associated with illumination, spiritual growth, and cleansing negative energy. In modern crystal healing practices, it is believed to integrate energy on all levels and is linked to the solar plexus chakra.
