Even when compared to silver or bronze though. In processing it as gold jewelry, you have to go through several stages, starting with mixing gold with a purity of 90% with gold of lower purity.
After that the gold will enter the washing and melting process. This stage also functions to separate gold from other rocks that are not needed. The end result of this melt is pure gold ore, which can be used as raw material for jewelry. The final stage remains to be formed according to customer orders and wishes.

Mined for further jewelry is diamonds. Diamond processing seems to be the longest compared to the others. The manufacture of diamonds as a result of mining for jewelry starts from the process of marking or taking photos of the raw form of diamonds.

The next step is to create a 3-dimensional sketch, in order to determine what shapes and patterns match the size of the diamond. Then proceed with cutting using a special laser, to ensure the shape obtained is precise and in accordance with the initial sketch.
This cutting is not done manually, but using a special printing machine. After the laser is finished, the diamond will go into the process of re-checking, ensuring whether there are still parts that need to be polished or whose shape is less than perfect. After everything fits, the diamond is ready to go through the polishing process, and to be paired with the customer’s ordered jewelry.
