Lab-Grown Green Quartz (likely Green Glass or Smelt Quartz)
Synthetic Silicon Dioxide (Amorphous Glass or Hydrothermal Quartz) · Decorative Stone / Synthetic Simulant
Crystal System
Amorphous (Glassy) or Hexagonal (if Hydrothermal). This specimen is carved into a heart-shaped cabochon.
Mineral Group
Silicates (Tectosilicate group if crystalline; otherwise non-crystalline silicate glass)
Chemical Formula
SiO2 (with Chromium or Iron colorants)
Formation Process
Hydrothermal growth (man-made in high-pressure autoclaves) or industrial melting and quenching (cullet glass).
About This Crystal
Transparent, deep emerald-green heart-shaped stone with a vitreous luster. It appears exceptionally clean with no visible natural inclusions, characteristic of man-made materials.
Physical Characteristics
Color: Deep Green; Streak: White; Fracture: Conchoidal; Specific Gravity: Approx. 2.65; Fluorescence: Usually inert but can vary based on dopants.
Optical Properties
Refractive Index: 1.544-1.553 (Quartz) or approx. 1.50 (Glass). Singly refractive if glass, doubly refractive if hydrothermal quartz. No pleochroism.
Hardness & Durability
Origin Region
Mass-produced in laboratories or industrial furnaces, commonly in China or Russia. Modeled after natural Siberian Green Quartz.
Hardness & Durability
Mohs Hardness: 5.5 (Glass) to 7.0 (Quartz). Good durability for decorative use, though glass is prone to scratching and chipping.
Care & Maintenance
Wash with warm soapy water and a soft cloth. Avoid harsh chemicals and sudden temperature shocks. Store separately to prevent scratching.
Rarity & Value
Very Common. Mass-produced for the jewelry and craft market. Inexpensive, usually priced by the piece rather than by carat weight.
Special Characteristics
Perfect clarity and uniform color distribution differentiate it from natural green minerals like Emerald or Peridot, which typically show inclusions.
Lore & History
In modern crystal healing, green stones are associated with the Heart Chakra, representing growth and abundance. Historically, green glass was often used as a 'paste' simulant for emeralds.
