Quartz, Rutilated Quartz and Tourmaline Beads

Quartz is, after feldspar, the most abundant mineral on the earth crust. There are two big families within the quartz minerals: the macro-crystalline, mostly transparent varieties and the micro-crystalline (or crypto-crystalline), which are translucent or opaque. The opaque range includes agate and jasper.

Pure quartz or rock crystal is the colorless transparent variety. Colored quartz goes by a lot of different names such as amethyst, citrine, rose quartz, and so on. More on rock crystal on http://dunebeads.com/en/the-birthstones-april-about-innocence-love-and-shhh

Tourmaline exists in a rainbow of colors and from milky white to black. Black opaque tourmaline is also called Schorl (from the german Schürl or Schörl). More about the lucky stone of October on http://dunebeads.com/en/the-birthstones-october-about-hope-opal-and-tourmaline
