Crystals
Amethyst
Colour	Voltage	Frequency
	0.03 volts	66 hertz
	0.02 volts
The voltage of the inside of the Amethyst does not increase of voltage on compression. The outside of the Amethyst increases to 12 volts.
Turquoise
Colour	Voltage	Frequency
	1.2 volts	66 hertz
The voltage of the Red Jasper area increased to 1.5 volts on compression. On continuous compression the voltage drained to 0.7 volts.
Clear Quartz
Colour	Voltage	Frequency
	0.5 volts	66 hertz
The voltage of the Clear Quartz area tripled to 1.5 volts on compression. On continuous compression the voltage drained to 0.2 volts
Rose Quartz
Colour	Voltage	Frequency
	0.06 volts	66 hertz
	0.3 volts	66 hertz
	0.6 volts	66 hertz
Compressing the Rose Quartz area generated very different voltage differences in the White and Pale Pink areas. The voltages of the Dark Pink area doubled to 1.2 volts on compression.
Smoky Quartz
Colour	Voltage	Frequency
	0.3 volts	66 hertz
The voltage of the Smoky Quartz area quadrupled to 1.2 volts on compression. On continuous compression the voltage drained to 0.1 volts.
Red Jasper
Colour	Voltage	Frequency
	0/3 volts	66 hertz
The voltage of the Red Jasper area doubled to 0.6 volts on compression. On continuous compression the voltage drained to 0.15 volts.
Orange Calcite
Colour	Voltage	Frequency
	0.18 volts	66 hertz
The voltage of the Orange Calcite increased to 0.24 volts on compression. On continuous compression the voltage drained to 0.1 volts.
Wood
Colour	Voltage	Frequency
	2.5 volts	66 hertz
