Milky Quartz: Cloudy White Variety of Quartz

Milky quartz, also known as snow quartz or white quartz, is a translucent to opaque variety of quartz, the most common mineral on Earth.

Milky quartz is sometimes called "dairy quartz" or "milk quartz" because of its milky appearance.

The milky appearance of milky quartz is attributed to the presence of microscopic fluid inclusions and tiny gas bubbles trapped within its crystalline structure. These inclusions scatter light, giving the quartz its characteristic milky white appearance. The color of milky quartz can vary from a faint white to a deep milky white, depending on the concentration of inclusions.   

Milky quartz is found in a wide variety of geological settings, including hydrothermal veins, pegmatites, and granites. It is also a common component of sedimentary rocks, such as sandstones and conglomerates. Milky quartz is found all over the world, and it is one of the most abundant minerals on Earth.
