Ada Diamonds’ jewelry design and fabrication processes celebrate and support the belief the fine jewelry production is a form of art.

It takes natural talent as well as years of mentorship and experience to develop the skills required to design beautiful jewelry, flawlessly cast settings in precious metal, and meticulously set diamonds in jewelry by hand. A complex design can take over 100 hours of labor to design and fabricate.

Ada has sought out the most talented artisans to fabricate and create all of our jewelry in the United States. Ada delivers superlative jewelry to the most discerning customers and refuses to compromise on the quality of our setting. In other words, the quality of our jewelry must match the quality of our diamonds.

In order to achieve this level of quality, the majority of our pieces take four to six weeks to fabricate. We leverage technology to accelerate our communication and logistics processes as much as possible, without taking short cuts during the artisanal process. If you are working on a different tighter timeframe, one of our concierge members is happy to discuss what options are available with a quicker turnaround. 


Our Jewelry Production Process

Designing Jewelry: We have sought out the best jewelry designers from around the world. Ada designers will often start with hand-drawn pencil sketches of designs, and then create a computer model using modern CAD software.  


Iterating with Customers: For custom designs, Ada Concierge members and Designers work hand-in-hand with the customer’s feedback to perfect the jewelry design. 


Printing the Wax Model: Once the design is complete, and a 3D model has been rendered, our fabricator will print a 3D model—the wax model—to ensure that is ready for casting. 


Creating the Shell: To create a mold or shell to cast the jewelry, the fabricator hardens a liquid material around the wax model, and places it in a high-temperature kiln. In the kiln, the wax melts out of the shell, leaving a void in the shell that is the exact shape of the finished piece.


Casting the Metal – After it is tested and cleaned, the shell is placed in a centrifuge and spun at 20 times the force of gravity to ensure that molten recycled 18K gold or platinum completely fills the void in the shell. After the metal and the shell cool to room temperature, the shell is removed, leaving just the gold or platinum setting. 


Polishing - The metal setting is then polished for hours by an expert goldsmith. They will use fine-grained materials to remove any artifacts from the casting process and polish the jewelry to a beautiful mirror-like finish.


Diamond Setting - After the jewelry is polished, the diamond(s) are hand set by an experienced bench jeweler who gently bends the metals around the gemstones to ensure that they are aligned as designed and secure. For jewelry with many small diamonds, the setting process can take multiple days of careful labor to get each gemstone perfectly set.


Final Polish and Plating - After the diamonds are set, the metal receives one last cleaning and polishing.  For white gold and black gold jewelry, there is one additional step in the process - rhodium plating, which creates a surface that is resistant to scratching and tarnishing. Since Rhodium plating protects your jewelry, but does not last forever, Ada Diamonds recommends having your white and black gold jewelry plated every 3-20 years depending on use. We offer this service for free for life. 


Photography - As a last step in the design process, Ada Diamonds will take high quality pictures and videos of your finished jewelry with professional camera equipment, which you can choose to use as you see fit. We recommend you share them with your insurance company if you choose to insure your Ada Diamonds jewelry. 


Packaging and shipping - A member of the Ada team will clean your jewelry one final time before placing it in our custom jewelry box and shipping it to you.
