Clear to cloudy quartz
Clear quartz is a quartz variety whose appearance can range from transparent-looking sections to cloudy areas with visible internal details. A polished surface or shaped point offers a particular view of those features. Clarity as a symbolic idea is separate from transparency as an appearance detail; neither establishes an effect on the mind or another object.
Personal symbolism
In contemporary crystal symbolism, clear quartz is associated with clarity and intention. These are personal or cultural associations. Someone may choose a piece as a reminder of those values, without expecting the material to produce a physical or emotional effect.
Looking at a finished piece
Transparency is only one part of the appearance. Internal lines and cloudy patches can be part of the visual character; compare the actual item photographs and stated finish.
Before choosing a piece
Read the stated material, dimensions and construction of the actual item. Keep the care directions for its setting, cord or other components as well as the stone. Store finished pieces so that they do not strike one another, and choose a stable location for decorative objects.
