Jewelry Manufacturing Process

Jewelry design

We specialize in personalized designs that cater to your specific preferences, whether you provide us with samples or original sketches developed at your request.
Understanding the essence of creativity in jewelry design, we welcome a diverse range of referenced data and information from designers, including CAD files, PDFs, hand-drawn drawings, and even spoken explanations accompanied by pictures found online. Our talented artisans are adept at transforming your imaginative ideas into exquisite works of art.

Jewelry 3D design

Extra Spark’s jewelry design team can transform your ideas into reality using CAD (Computer-Aided-Design) models that optimize quality and minimize costs while bringing your vision to life. Starting from simple napkin sketches, our team employs various techniques, including hand drawings, CAD drafting, 3D printing, and modeling during the development stage. Your design will be brought to life through detailed 2D and 3D models, and you also have the option to purchase a prototype to assess the quality and attention to detail before placing a larger order.

Jewelry Prototype

While traditional jewelry design techniques like hand sketching and drafting continue to be prevalent in the jewelry manufacturing industry, we have adopted computer-aided design (CAD) software tools for creating distinctive jewelry prototypes. Utilizing CAD models for rings, bracelets, earrings, and other jewelry types allows for easy replication through computer-controlled production processes. This approach simplifies the manufacturing process compared to traditional methods, which require a high level of skill to minimize errors and save time.

Jewelry Casting

During this phase, we create wax pieces using rubber molds derived from the silver master. The rubber mold is placed onto a commercial wax injector machine, where molten wax is injected under pressure into the mold cavity to produce wax models for the casting process.

Jewelry Filling

Precious instruments are employed to meticulously fill and shape the metal, achieving the desired product form with precision. The filling process involves removing any excess metal and refining the surface to create flawlessly crafted jewelry pieces. This critical step guarantees that each item reaches its finest state and meets the highest quality standards.

Jewelry Stone Setting

Our expert craftsmen excel in skillfully and securely setting stones, ensuring both precision and efficiency in the process.

Jewelry Polishing

The polishing process involves multiple stages, meticulously executed to achieve a flawless finish for each piece. Various materials are used to ensure proper polishing, resulting in a shining, blemish-free metal that exudes a high-end appearance. High-speed polishing equipment and cleaning baths are commonly utilized to achieve the desired level of refinement.

Quality Control

At every stage of production, rigorous quality control measures are implemented, culminating in a final pre-shipment check. Professional jewelers uphold strict standards, ensuring that no gold jewelry is sold without undergoing meticulous inspections. Once the entire process is completed, a dedicated team of specialists carefully examines each jewel, meticulously looking for any faults or blemishes to guarantee the highest level of craftsmanship before shipment.
