Gemstones in Georgia: Where to Find Them

Georgia may not be the first place that comes to mind when you think of precious gemstones, but the state is home to a wealth of geological wonders waiting to be discovered. From Troup County to

Fannin County and beyond, rockhounds and gem enthusiasts will find an abundance of treasures.

In this article, we will explore the best places to go rockhounding in Georgia and the gemstones that can be found there.

Best Places for Rockhounding in Georgia

Troup County

Located in western Georgia, Troup County is known for its Hogg Mine – famed for producing stunning gems and crystals. These include aquamarine, amethyst, rose quartz, black tourmaline, and beryl.

These majestic beauties can be found inside the mine or through digging in the surrounding dirt. Its important to note that the Hogg Mine is privately owned, so access is only available during organized rockhounding events.

Fannin County

Fannin County is a mecca for rockhounds seeking staurolite and Fairy Crosses. Both are found within metamorphic rocks, along with almandine garnets.

The Fairy Crosses are six-sided crosses formed by the intersection of two separate staurolite crystals. As a result, they have a legendary reputation for bestowing good luck upon those who find them.

The garnets in

Fannin County can be found in the same metamorphic rocks containing the staurolite.

Lumpkin County

Lumpkin County was the site of Georgias gold rush and is part of the Georgia Gold Belt. The gold can be found in quartz and granite formations, as well as diorite and gneiss.

While this area may be more challenging for the amateur rockhound, it provides a window into the history of Georgias gold-mining past.

Gemstones in Georgia

Amethyst

Citrine is a type of quartz that ranges from a pale yellow to a deep amber color.

Citrine is found in quartz veins associated with amethyst and aventurine deposits.

Moonstone

Moonstone is a pearly-white mineral that glimmers with iridescent flashes of blue, green, and pink. It is found in the Piedmont region of Georgia in feldspar minerals.

Garnet

Garnets are found throughout Georgia in metamorphic rocks such as schist, gneiss, and mica schist. Different varieties and colors of garnet can be found in different areas of the state.

Rose

Quartz

Rose

Quartz is a lovely pink variety of quartz that can be found at the Hogg Mine in Troup County and other areas of Georgia. It is often associated with aquamarine and other minerals.

Quartz

Quartz is one of the most abundant minerals on Earth and can be found in nearly every part of Georgia. The most common form of quartz found in Georgia is milky quartz, but other varieties such as citrine and amethyst can also be found.

Peridot

Peridot is a bright green gemstone that is found in mafic and ultramafic igneous rocks. While peridot is not as common in Georgia as other gemstones, it can be found in certain areas.

Ruby and Sapphire

Both of these beautiful gemstones can be found in Georgia, but they are rare. Rubies have been found in the Cowee Creek area of Macon County, while sapphires have been found in the mountains of north Georgia.

Georgia has a rich history of gold mining, dating back to the 1800s.

While commercial gold mines are now inactive, recreational gold panning is still a popular activity in the mountains and streams of northern Georgia. In this section, we will explore the recreational gold panning scene in Georgia, how to get started, and what to expect.

Recreational Panning

Recreational gold panning is a popular pastime in Georgia, with many prospectors scouring the creeks and streams for specks of gold. Recreational panning is allowed in some areas of the state, but it’s essential to check with local authorities before panning to avoid breaking any laws.

Commercial Gold Mines

While commercial gold mining is no longer active in Georgia, visitors can still tour several sites to learn about the history of gold mining in the state. The Consolidated Gold Mines in Dahlonega, for example, offers underground tours of the mines as well as gold panning activities for visitors.

Stream Beds

Streams and rivers are the most common sites for recreational gold panning in Georgia. Prospectors typically look for areas with a good flow of water and plenty of exposed bedrock.

The flow of water helps to wash away the lighter sediments, leaving the heavier gold particles behind. Popular locations for gold panning include the Chattahoochee River, the Chestatee River, and the Etowah River.

Equipment

Recreational gold panning doesn’t require a lot of equipment. Prospects typically use a small shovel or trowel to dig up gravel and sediment, a gold pan to separate the gold from the sediment, and a snuffer bottle to suck up any gold flakes or dust.

Some prospectors also use a
