Strawberry Quartz
Quartz var. Strawberry Quartz · Semi-Precious Gemstone and Decorative Stone
Crystal System
Trigonal system; typically massive, tumbled, or carved into decorative shapes.
Mineral Group
Silicates (Subgroup: Tectosilicates)
Chemical Formula
SiO2 with inclusions of Lepidocrocite, Hematite, or Goethite
Formation Process
Hydrothermal and pegmatitic formation where growing quartz crystals trap microscopic red to brown mineral inclusions such as lepidocrocite, hematite, or goethite within the crystal lattice.
About This Crystal
The specimen is a hand-carved decorative shape (resembling a stylized animal skull) made of translucent pinkish-red quartz. It displays a vitreous to waxy luster, smooth polished surfaces, and tiny internal reddish-brown speckles or inclusions characteristic of strawberry quartz.
Physical Characteristics
Body color ranges from pale pink to reddish-brown due to inclusions; white streak; completely lacks cleavage; exhibits conchoidal fracture; specific gravity is approximately 2.65; brittle tenacity; displays piezoelectric and pyroelectric properties.
Optical Properties
Singly or weakly doubly refractive with a refractive index of 1.544 to 1.553; birefringence is low at 0.009; generally non-pleochroic; the visual effect is driven by the scattering of light off internal mineral platelets producing a shimmering or glittering appearance known as aventurescence in some specimens.
Hardness & Durability
Origin Region
Notable sources include Russia, Kazakhstan, Brazil, and Madagascar. Forms in pegmatites and hydrothermal environments.
Hardness & Durability
Mohs hardness of 7, making it durable enough for everyday jewelry wear if set properly. Good toughness, though internal fractures or dense inclusions can create weak points.
Care & Maintenance
Clean with warm soapy water and a soft brush. Avoid ultrasonic cleaners and harsh chemicals or prolonged direct sunlight to prevent potential fading or damage to internal inclusions.
Rarity & Value
Uncommon to Rare, depending on the density and beauty of the internal inclusions. High-grade natural material with clear quartz and distinct red inclusions commands higher prices. Common quartz treatments like dyeing are occasionally used on low-grade stones to mimic this appearance.
Special Characteristics
Characterized by vibrant red to reddish-brown micro-inclusions (hematite, lepidocrocite, or goethite) suspended within a clear or milky quartz matrix, often creating a glowing or dotted internal texture.
Lore & History
Widely used in modern crystal healing as a stone associated with universal love, emotional balance, and the heart chakra. Though it lacks deep historical roots in ancient lore compared to other varieties of quartz, it is highly valued by contemporary collectors and practitioners for its unique appearance.
