The Meaning Of Milky Quartz

Milky Quartz -The stone of Tour

Milky Crystal, Long ago, people believed that milky crystal was a compact form of ice: crystallos actually means "frozen." The best milky crystal has the Milkiness and shimmer of crystal clear water.
Although milky quartz is relatively common, large specimens are not, which is why most crystal balls these days are made of glass, not quartz. Milky Quartz is highly useful in healing, in meditation and for spiritual growth and enlightenment. 

Milky Quartz is the ultimate "anything-stone" as it radiates all the color vibrations within the spectrum of light and thus can be utilized and programmed for any use which brings light and energy into our spiritual bodies. A "stone of the mind", quartz can be used to imprint with any energy or information and helps to focus the mind, aides in concentration and enhances mental ability. Milky Quartz is a power stone that harmonizes and balances. It enhances energy and thoughts, and purifies the spiritual, mental, and physical. It is also a powerfully protective stone, bringing the purified energy in. Historically this crystal has been used to counter black magic, to perform diagnostic healing, and to communicate with spirits and other worlds 

Milky Quartz is probably the most versatile, multipurpose, powerful healing stone on the planet due to is unique helical spiral crystalline form. It is a master healer and can be used for any and all conditions.
