WebSep 21, 2012 · Kyanite is one of the stones with the most unusual characteristics. Kyanite has anisotropism, meaning that depending on the direction it is measured, it gives different results. For example, depending on the direction the crystals are facing in its makeup, kyanite can rate a 4-5 to a 6.5-7 on Moh’s scale. Kyanite is also very brittle. WebA wide variety of minerals occur in Virginia. These minerals form the basic building blocks of the rocks that shape the landscape. Minerals exhibit distinctive properties that makes each unique. In Virginia minerals are mined for industrial purposes, collected by enthusiasts, and used for scientific research to help us better understand the Earth.
