A Writers Guide to Quartz

Rock Crystal

Rock Crystal

Quartz is the second most abundant mineral. It’s made of a continuous framework of SiO4 silicon–oxygen tetrahedral. Pure quartz is called rock crystal or clear quartz. It is colorless and transparent or translucent.

However, there are many varieties of quartz and it comes in most all colors. The biggest distinction between the types involves whether the crystals are visible to the unaided eye or if magnification is needed.

The name quartz comes from the German word quarz and the Middle High German word twarc meaning “hard.”

Major Varieties of Quartz

  • Amethyst: purple, transparent
  • Aventurine: green, orange, brown, yellow, blue, gray, translucent
  • Citrine: pale yellow to brown, transparent
  • Chalcedony: various colors (well-known varieties include agate, aventurine, carnelian, and onyx)
  • Jasper: various colors, opaque
  • Milky quartz (also known as snow quartz): white, translucent to opaque, may display diasterism*
  • Prasiolite: mint, very light green, transparent
  • Rock crystal, quartz crystal, or clear quartz: colorless and transparent or translucent
  • Rose quartz: pale pink to rose red, translucent, may display diasterism*
  • Rutile Quartz: quartz with needlelike rutile embedded in it, rutile may be reddish, golden, silvery, or on rare occasions, greenish.
  • Smoky quartz: gray to brownish gray, translucent
  • Tiger’s Eye: gold to red-brown, opaque, exhibiting chatoyancy**

Take note that there are a lot more types out there.

*Diasterism is an optical phenomenon resulting from light shining though the stone in a star shape. In order to see this effect, the stone must be illuminated from behind.
**Chatoyancy is a luminous streak of reflected light that is perpendicular to the direction of the fibers.

(In stone therapy, when using stones to heal, their energy is used up, requiring the stones to be recharged.)

  11. I wonder if anyone has been working on a quartz-powered electric car? Or quartz for other energy generating purposes? This series is mind stimulating.
