The Mining and Production Process for Gemstones in Africa
The mining and production of gemstones in Africa is a complex process that involves a variety of methods. Some of the methods used to extract gemstones in Africa include:
- Open-pit mining: This method involves the excavation of an open pit in the ground to access gemstones that are found close to the surface. This method is often used for gemstones that are found in large, easily accessible deposits.

Once the gemstones have been extracted, they go through a series of steps in the production process, including:
- Sorting and grading: The gemstones are sorted and graded according to their quality and size.
- Cutting and shaping: The gemstones are cut and shaped into the desired size and shape using specialized equipment and techniques.
