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.

Recycled Metals: Responsibly sourced for a brilliant future

Ada Diamonds Recycled Metals



Today's technological achievements allow Ada Diamonds to turn abundant natural carbon sources into diamonds, but we cannot yet turn lead into gold. As we call for end to the devastating practice of diamond mining, Ada Diamonds is committed to sourcing gold and other metals produced under the highest social, human rights, and environmental standards. We are working toward using 100% recycled materials in all of our jewelry, and guarantee that all of our earth-extracted gold and platinum has been mined sustainably and responsibly.


We know your lab grown diamond purchase is an investment in a cleaner future. As part of our commitment to a brighter world, we are signatories of the No Dirty Gold Pledge and wherever possible utilize gold and platinum that is recycled in America, processed in America, and cast in America to the highest environmental standards. In fact, we obtain much of our platinum from catalytic converters of recycled or junked cars. These metals are carefully re-refined into their pure form and cast into settings for our conflict free diamonds.



Mining of gold and other precious metals has historically been associated egregious human rights abuses, child labor and low wage workers toiling in unsafe conditions. Ada Diamonds is committed to ensuring there is no exploited labor in our supply chains by souring only laboratory grown diamonds and responsibly sourced precious metals. Ada Diamonds requires all of our suppliers to certify that their labor forces are made up of adults of legal working age who are working of their own free will. 


The Golden Rules: Ada's Gold and Precious Metals Sourcing Policy

Our commitment to responsible sourcing is at the heart of everything we do. Click below to read the our commitment to the The More Dirty Gold Pledge in it's entirety. 

Ada Diamonds is concerned about the environmental and social impacts of irresponsible mining practices. We are committed to sourcing gold and other metals produced under the highest social, human rights, and environmental standards. We are working to ensure that the gold and other metals in our products were not produced at the expense of communities, workers, or the environment. Therefore, our company is pleased to announce that we will join the industry’s environmental and social leaders by taking the following steps:

We will immediately undertake an audit to determine the sources for all of our gold products. Our supply chain audit will include information about how gold is being mined, refined, and manufactured. We will share the relevant results of this audit with
the No Dirty Gold campaign.

  • We will work to ensure that the gold and metals we purchase come from sources that meet the highest human rights, social, and environmental criteria at all stages in the supply chain (mining, processing, refining, recycling, etc). These criteria include, but are not limited to:
  • Ensuring that gold or other metals were not obtained from operations using submarine or riverine tailings disposal (i.e., the dumping of mine wastes in the ocean, coastal waters, and rivers).
  • Ensuring that basic human rights (as outlined in international conventions and declarations such as the UN “Universal Declaration of Human Rights,” and others) are being respected by all parties involved in the mining, processing, and manufacturing of the products we sell.
  • Ensuring that gold is being sourced from mines that were built and are being operated with the free, prior, and informed consent of local communities.
  • Ensuring that workers’ rights and labor standards (including the eight core ILO conventions) are being respected by all parties involved in the mining, processing, and manufacturing of the products we sell.
  • Ensuring that gold is not being sourced from areas of armed or militarized conflict.
  • Ensuring that gold has not been sourced from protected areas or areas of high conservation or other ecological value.
  • Ensuring that gold has not been sourced from mines that have been responsible for the forced displacement of communities.
  • Ensuring that gold has not been sourced from operations that will result in sulfuric acid or toxic chemical contamination into soil, surface waters, groundwater, or the environment.
  • Ensuring that gold is being sourced from mines that have provided full financial guarantees to cover the costs of clean-up and mine closure.

We will seek independent, third party verification that gold and other precious metals we purchase meet these and other criteria.

We will immediately inform suppliers of gold and other precious metals at all our facilities worldwide that we intend to purchase these metals from sources that meet the above criteria. We will include relevant language in all contracts with suppliers.

We are committed to increasing our sourcing of gold from recycled and secondary sources, and we will set targets for increasing the use of these sources. We will seek independent, third-party verification of secondary content.

Our corporation is committed to implementing policies that promote the more responsible production of gold and precious metals. We are committed to serving as a leader within our sector, not only through our purchasing behavior, but by encouraging other companies within our industry to do the same.
