Quartz includes a variety of stones and colorless, or crystal quartz is the most common. Brazil is a major supplier of crystal quartz. Especially when it comes to verities with mineral inclusions. Quartz is found abundantly throughout the world, including in the United States. The word "crystal" comes from the Greek word for "ice" and was believed to be eternally frozen. The single quartz crystal is a six-sided prism, however this is not always how it is formed. Sometimes it is found in veins, seams, or pockets containing the massive variety.
