Gemstone manufacturing

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:

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.
