Jasper is a chemical sedimentary rock made of cryptocrystalline
(very fine-grained) quartz. 
It is distinguished from chert and jasper by its strong coloring
which comes from iron compounds, making it red, orange, yellow,
green, or brown.                                                                                   
Red is the most common color associated with jasper.
