Georgia State Mineral: Staurolite
Staurolite is a dark crystal, usually red or black, that often forms in a twinned or cross-shaped formation. Staurolite crystals are sometimes called "fairy stones" or "fairy crosses," and are often kept as good luck charms.

Georgia's Highest and Lowest Elevations
Highest Elevation: Brasstown Bald
The Chattahoochee-Oconee National Forest is home to Brasstown Bald, Georgia's highest mountain. At 1458 meters (4784 feet) in elevation, the peak offers 360 degree views of four states—Georgia, North Carolina, Tennessee, and South Carolina—and on clear days, even the skyline of Atlanta is visible.

Lowest Elevation: Atlantic Coast
Georgia's lowest points are found at sea level along the coast, where the shoreline meets the Atlantic Ocean.
