Custom Jewelry Making using Lost Wax Casting


Custom Jewelry Making using Lost Wax Casting


Sketch of custom ring design

The first step in making custom jewelry is you, the customer, getting the idea of a ring, earring or pendant design you would like to have created.  Usually you have looked for that special piece of  jewelry but can't find the design you want anywhere.  Once you contact me, jewelry maker Tony Payne, and explain what you want, I will give you a free price quote based on your unique design ideas. A sketch of the design can be made for your approval before any work begins.


The next step in the custom jewelry process is carving the wax model. For a video of me demonstrating this step in the process go to this YouTube page. Rings start out as wax tubes and pendants begin as wax sheets or blocks. Saws, files, and specialized carving tools are used to cut away the wax and sculpt the design.

Measurements are taken and the design is first scratched in the surface of the wax model. As in most sculpture the material that is not needed is removed.  Wax can also be added to the design using a special tool.  Once the design is carved, sprues, or wax wires, are added which will be attached to a flexible rubber base (see below). The wax is weighed and multiplied by a factor to see how much gold or sterling silver will be needed to make a complete cast.


The wax model is then attached to the rubber base using the wax sprue. More than one model can be attached to each base if needed.  A metal flask is then put into the rubber base.

Investment is a white powder used in casting that is mixed with water.  The investment is mixed using exact proportions, stirred and then poured into the metal flask. This material is semi-liquid when first mixed and it engulfs the wax model and sprues. It is then left for an hour to harden. The wax model and sprues are encased inside the hardened investment.

The rubber base is removed and the flask containing the wax is placed in a burnout oven. This burnout process takes about six to twelve hours to complete and reaches a maximum temperature of 1350 degrees Fahrenheit. The wax model is destroyed by this extreme heat leaving a cavity where it once was.  The flask is taken out of the oven and molten gold or sterling silver is immediately poured into the cavity in the investment. The sprues now act as channels for the molten gold.  The metal then cools and hardens.



After the metal cools the sprues are sawed off and the metal design is smoothed with files and then sanded. The piece is polished and given any finishes that are needed such as texturing or antiquing. Any gemstones are then set in the handmade ring, pin or pendant. This completes the ancient custom jewelry making process know as lost wax casting.  The results is a finished handcrafted ring, bracelet or pendant that is unique and will always have special meaning to the person that wears it.

Custom Africa Pendant made in Sterling Silver


Unique Handcrafted Africa Pendant


This Africa custom pendant I recently made for an Internet customer of mine. This unique handcrafted pendant was done in sterling silver and is two inches tall and weighs 23.5 grams.



Have you looked everywhere for that special piece of jewelry and can't find what you want? Are you tired of wearing the same jewelry everyone else is wearing? Let Payne's Custom Jewelry help you make your own fashion statement by creating the custom jewelry you've always wanted. You can wear unique designer jewelry that no one else in the world has!


I have been making unique custom jewelry for over 25 years and use the lost wax casting method to make my jewelry. Each ring or pendant is first hand carved in wax and then cast in the precious metal of your choice.


Email me at tony@paynesjewelry.com and I will give you a free price quote based on your jewelry design ideas. I can send a sketch of the design, for your approval, before any work begins. I will email you pictures of the progress on the wax model of your custom ring or pendant.

My labor charge is based on the complexity of the design and starts at $150 for custom pendants and $250 for rings. I can make your jewelry in either sterling silver, yellow or white gold or platinum. The prices for the metal are based on current market conditions. I can use any gemstones you like in the design.
