Creating a gemstone involves several processes, from mining to the final cut and polishing. Here’s a simplified flow chart outlining the typical steps in the gemstone manufacturing process:
Flow chart
RECEIPT OF ROUGH FROM MINS
- Gemstones are often extracted from mines or deposits in the earth.
- Miners extract raw gemstone material, which can include crystals or rough stones.
↓
INITIAL ASSORTMENT KNOCKING OF STONE AND GRAGING
- The extracted gemstone material is sorted based on quality, size, and color.
- Cleaning processes may be employed to remove dirt and impurities.
↓
SIZING OF ROUGH
- it involves shaping the raw material into a more manageable and workable form before the faceting and polishing stages. The goal is to maximize the yield of high-quality gemstones while minimizing waste.

DOPPING
- Dopping is the process of attaching the preformed gemstone to a dop stick or holder using a special wax or epoxy.
- The dop stick provides a handle for the gemstone during the faceting process.

CLEAING CLEAING
- After dedopping, the gemstone may have residual wax or epoxy on its surface.
- The gemstone is cleaned to remove any remaining adhesive material. This can be done using solvents or other cleaning agents.
