Physical properties
Hardness: 6.5 to 7 (for quartz varieties), 2-3 (for mica/fuchsite). Colors: Pale pink, silvery-green, and dark forest green. Luster: Vitreous to pearly. Crystal Structure: Hexagonal/Monoclinic.
Formation & geological history
Formed in pegmatites, hydrothermal veins, and metamorphic rocks. Most specimens date from hundreds of millions to billions of years old depending on the location of deposit.
Uses & applications
Primarily used for ornamental purposes, lapidary work, jewelry, and by collectors for metaphysical or aesthetic value.
Geological facts
The pink color in the rose quartz is caused by trace amounts of titanium, iron, or manganese. The green color in the fuchsite and aventurine is primarily due to chromium content.
Field identification & locations
Identify by color and hardness (quartz will scratch glass; fuchsite will peel in flakes). Common in Brazil, India, and South Africa. Collectors should look for vibrancy of color and clarity.
