People tend to ask the following question. Where do geodes come from?
Take a quick tour of the World Famous Las Choyas Mine. It has been mined for the past 40 years. This type of geode is one of the most unpredictable in the world, meaning that you never know what treasure is found inside. There are dozens of different mineral formations that can occur inside this specific type. In the following are pictures of the mining operations that take place just to bring these beautiful geodes to you.
The geode bed runs 100 ft below the ground. A drilling machine is used to drill down to this layer.
This is what the mine shaft looks like once the drilling is complete.
Once the geode bed is reached tunnels are made by pick and shovel.
The excess material is taken out by wheelbarrow.
Geodes are found embedded in the white clay which was once volcanic ash.
Once enough geodes are gathered they are sacked and lifted to the surface by a motorized winch. From here they are hauled to the warehouse, sized and sorted for hollowness. 80 % of what comes out of the mine is solid quartz or agate and only 20% is either hollow or semi hollow.
Then they are transported to the sorting facility where they are hand sized and hefted to determine which ones are hollow. Gem Center USA is one of the only companies that guarantees the geodes to be 95% hollow.
Gem Center USA then distributes the geodes all over the world.
