Milky quartz, often referred to as white quartz, is a silicon dioxide mineral distinguished by its translucent to opaque white coloration. This hue is a result of microscopic fluid inclusions trapped within the crystal structure during its formation. These inclusions can be water, gas, or even other minerals, scattering light and giving the quartz its milky appearance. Variations in clarity, from almost transparent to fully opaque, are common. This readily available and affordable stone finds diverse applications, ranging from jewelry and ornamental carvings to industrial components in electronics and optics.
The durability, abundance, and piezoelectric properties of this variety of quartz have made it a valuable material throughout history. Its ability to generate an electrical charge under mechanical stress makes it essential for timekeeping devices like watches and clocks, and critical in applications requiring precise frequency control. Beyond its industrial significance, milky quartz has also held cultural and spiritual meaning across various societies, often associated with purity, clarity, and healing. Its aesthetic appeal makes it popular in decorative arts and architecture.
