Quartz is the most common mineral on Earth. It is found in nearly every geological environment and is a component of almost every rock type. It makes up about 12% of the earth's crust, occurring in a wide variety of igneous, metamorphic and sedimentary rocks. It is also the most varied in terms of variety and color. Quartz is a 7 on the Mohs scale of hardness.
Rutilated quartz is found in Australia, Brazil, Kazakhstan, Madagascar, Norway, Pakistan and the United States.
Rutile is a major ore of titanium, which is a metal used for high tech alloys. It often forms needle-like crystal inclusions inside quartz. This form of quartz is known as rutilated quartz and it looks like small bars of imbedded needles. Rutile is a 6 on the Mohs scale.
Because of the difference in hardness between the two materials and because of the way rutile forms inside, this can be a difficult stone to attain a smooth surface without pits.
