These are Clear Quartz stones that have been dyed bright and fun beautiful colors. Clear Quartz is sometimes called ‘Rock Crystal,’ and is the stone most often thought of when the term ‘Quartz’ is used. Quartz is the most common mineral on the face of the Earth, found in nearly every geological environment and almost every rock type. It is also the most varied, with many varieties, colors, and forms. Quartz crystal exhibits the property of piezoelectricity, by which it can transform mechanical energy (e.g. pressure) into electromagnetic energy, and vice versa. This makes it useful in such devices as crystal radios, microphones, watches, radio transmitters, etc.
Rock is approximately 1" to 2" in diameter and weighs roughly an ounce. Quartz varies in colors.
