Characteristics of Specific Minerals and Gemstones

Georgia is home to a variety of unique minerals and gemstones, each with its distinctive physical and chemical properties. Here’s a closer look at some of the most notable minerals and gemstones found in the state.

Staurolite: A Crystalline Mineral with a Unique Form

Staurolite is a fascinating mineral that is commonly found in the schist and gneiss rock formations of Georgia. It is a hard mineral, typically rated at 7 on the Mohs scale, and is known for its unique form, which is often shaped like a cross.

This characteristic form is due to the habits of staurolite crystal growth, as well as its distinctive twinning. Because of its hardness and unique form, staurolite has been used as a depth marker in the construction of dams.

Marble: A Versatile Stone with moderate hardness

Marble is a metamorphic rock that is formed from the recrystallization of limestone. In Georgia, marble is primarily mined from the north-central and northwestern regions of the state.

Commercially, marble is primarily used in the construction of buildings and as decorative stones, due to its moderate hardness, which makes it easy to carve and shape. Georgia’s marble, which is known for its consistency and color purity, has been used in many significant structures and monuments throughout the world.

Calcite: A Highly Crystalline Carbonate Mineral

Calcite is a carbonate mineral that is heavily crystallized in Georgia. It is commonly found in limestone and marble deposits and is used in a variety of industrial applications.

The specific gravity of calcite makes it ideal for use as a filler in paints and other chemicals. This versatile mineral is also commonly used as a decorative stone in the construction industry.

Barite: A Dense Mineral with Industrial Value

Barite is a dense mineral that is commonly found in Georgia. It is the primary source of barium, as well as celestine and anglesite.

Due to its ability to block x-rays, barite is commonly used in the petrochemical industry for drilling operations. Celestine and anglesite, on the other hand, are used in the production of lead-acid batteries and other industrial applications.
