Clear Quartz Sphere
Stone Source: Brazil

A few things come to mind as to what this sphere could be used for, but, nonetheless, this sphere is an amazing piece. It is extremely difficult to obtain the caliber of Quartz necessary to make a sphere greater than 3 inches (7.62 cm) in diameter with this level of optically flawless perfection anymore. It is well-polished with perfect concentricity: one can use this "crystal ball" as a lens as objects viewed through it are perfectly clear, just upside down. A word of caution applies: do not leave this sphere in sunlight - since it is a large and powerful sphere, it can magnify light and thus could start a fire unintentionally.
Overall Measurements: 3.25 inches (8.25 cm) in diameter
