Stages of Manufacture

Fine craftsmanship is the crux of every exquisite masterpiece.

Fine craftsmanship is the crux of every exquisite masterpiece. With our rich experience in jewelry making, we are working alongside renowned jewelry designers around the globe in designing, manufacturing, and distributing their production.

Inside our SMETA & ISO 9001 certified production facility located in Guangzhou, every piece of jewelry will be undergoing 10 development stages.

This video will help you understand our production in every step

01
DESIGN

As a member of RJC, Cattivo involves in the local community to donate material, people, and budgets to uphold our values of ethics, human rights, and the UN sustainable goals. Cattivo makes our actions into one of these chapters as a giveback to society for more sustainable development.

Meanwhile, during the COVID-19, Cattivo Jewelry donated our safety goods, Personal Protective Equipment (PPE), and face masks to other countries during such a difficult time. Cattivo believes the scattering of light will eventually outline a clear vision of a sustainable future.

02
WAX MODEL

Our experienced craftsmen incorporate the traditional technique to hand carve all the intricate details into the wax model. The model will be heated up in an oven, to create a duplicated master model filled with metal.

The master model is packed into a special kind of rubber and squeezed tight under high temperature and pressure. The rubber forms itself around the master model, creating a three-dimensional impression of the jewelry. The rubber is cut in half to remove the master model, and what we get here is a perfect rubber mould which can be duplicated for thousands of wax replicas for mass production.

03
TREEING

Multiple wax replicas are attached to a large branching wax tree. Creating a tree allows us to cast multiple jewelry pieces at once. The wax replicas are attached to a sprue, which is a thick straight cylinder wax rod and will eventually form a channel for the molten metal to enter the mould.

04
METAL CASTING

When the tree is completed, the whole wax structure is placed in a flask with a special kind of liquid plaster. The cylinder is then put into the oven, where the whole wax structure will be burnt away, leaving lots of jewelry-shaped void in the hardened plaster mould. The space is then filled with molten metal. Once the metal hardens, the mould is put into a bucket of cold water to dissolve the plaster, leaving the hardened metal tree and jewelry pieces. Individual pieces are separated from the tree and sent for finishing.

05
POLISHING

After the metalwork is completed, the next step is to polish the jewelry so as to produce the final high luster on the surface. Firstly, metal is buffed with soft rotary tools. Throughout the process, the wheels with various polishing compounds will be used to achieve the desired luster. Afterward, the metal is polished using harder compounds such as rouge. The rouge burnishes the metal, moving the surface layer around to smooth the fine scratches left from buffing.

06
STONE SETTING

T-bars, bails, hinges, and other components are precisely soldered into place. Afterward, gemstones of different shapes and colors are cut to size in in-house, and attached in the metal casting.

07
LASER
ENGRAVING

As a modern alternative to hand engraving, we use the laser to achieve complex engraving patterns as well as your brand logo, which are exceptionally precise and consistent.

08
OTHER
TECHNIQUE

At Cattivo, we provide a wide range of finishes that can bring your design to life vibrantly and elegantly. Examples include enamel, an opaque form of glass with a multitude of colors, and a variety of hammering and polishing finishes. Plating is also a great way to add breadth to your design. We provide plating options including white, yellow and rose, you can also select your preferred microns of coverage.

09
QUALITY
CONTROL

Every piece of jewelry is carefully examined by our quality controlling team. Any signs of porosity in the casting, such as little grains, voids, or bubbles that indicate that the hot gold didn’t properly fill the mold, would not be allowed.
