These sketches are designed for mass production in jewelry factories. In this section, I tried to apply the principles of aesthetics in jewelry in accordance with the common taste of the target community considering the capabilities and limitations of tools and equipment used in mass production. In the next step, these sketches are turned into 3D models through software like Matrix, and finally, prototypes are made by 3D printers. After that, they are cast with 18k gold, and in the end, stone setting and polishing are operated on them.
