anorthite crystal-1
Anorthite is the calcium end member of the plagioclase feldspars.  Large crystals
of anorthite are rarely found and the mineral is rather dull and uninteresting. 
However, it turns out that a large portion of the Moon's surface is made of anorthite. 
This specimen of anorthite is only about 1.5 centimeters.
