Quartz

Quartz is a commonly occurring variety of silicon dioxide. It often crystallizes into well-formed hexagonal prisms. Quartz occurs in many colors, purple amethyst, pink rose quartz, yellow citrine, and a smoky variety, referred to as smoky quartz. The colorless, transparent crystals represent the modern concept of “crystal”. Crystal balls with a mystic significance are made from quartz.

A BRIEF HISTORY OF QUARTZ

Examples of rock crystal objects date back to 75, 000BC. They are the earliest talismans known to man. Every civilization has attributed magical powers to quartz crystals. To the ancient Japanese it symbolized faith, perseverance, infinity and purity. Crystal balls were brought to Europe from the Near East by the Crusaders who credited them with the ability to cure diseases.

Ancient priests would use quartz crystals to light alter fires by focusing sunlight through the crystals. Quartz focused sunlight was also used for cauterizing wounds.

Roman ladies often carried quartz balls for both medicinal purposes and to cool their hands on warm days
