The Custom Jewelry Making Process:

The step by step process begins with the initial consultation. The client wants to bring a custom engagement ring or jewelry idea to life. It is the job of the designer to aid the client in making the process easy and to bring the desired design into life.

So the process begins.

Step one – CAD:

After the design is agreed upon and diamond or other gemstone is selected, the designer makes a sketch of the design. In our case, we make a CAD rendering design through a CAD software (examples shown above). It will show the client a three dimension view of the proposed ring or jewelry. While it will not look exactly as the final jewelry (the final product is always prettier), it will do the job of sufficiently showing the client how jewelry will look as well as to provide an opportunity for the client to make any changes to the design.

Step two – Wax:

Once the CAD is approved, the designer or goldsmith makes the wax. The wax is used to create an exact replica of the jewelry in a flexible and cost effective manner. Since wax is cheap, we don’t have to worry about making the piece perfect in the first attempt – it might take 2-3 attempts to make the right wax model for the mold. Wax is a life saver as it helps remedy any potential structural issues and smooths the surface to avoid too much polishing at the end of the process.

Step three – Making the Mold:

The third step is to put the wax into a plaster-based investment mold material to melt out the wax and make a hallow version of the jewelry. This step involves several tasks, including appropriately securing the mold, properly mixing the investment material, removing any air bubble from the investment mold through a vacuum chamber, pouring the investment mold mixture into a flask and allowing it to set, placing  the flask 1300 digress in kiln set, and finally checking the mold for any obstruction and removing the mask.

Step four – Casting the Jewelry:

In this step, the metal of choice is melted and poured into the mold. Once the metal is cooled off, it is removed slowly with the help of cold water.

Step five: Finishing the Jewelry:

In this step, a grinder is used to cut away any unwanted metal from the jewelry. An acid bath is also used to remove any remaining plaster from the jewelry. Once done with the initial cleanup, a metal buffing tool and jewelry polishing tool is used to finish the jewelry. Also, it will be extra work to add any stones or make prongs for diamonds and other gemstones depending on the jewelry/ring design. For white gold, radium platting would also be needed.
