Blue topaz stone is the best known of the many variants of topaz.

This stone can indeed take colors ranging from orange to pink through purple ; as explained in this complete article on topaz stone.

Topaz is particularly popular in making engagement rings. To break with the classic and expensive diamond so difficult to choose, the topaz stone can offer a very reasonable price for a large stone color pleasing to the eye, original which is as good with the yellow gold as white gold.

We will detail the manufacture of different designs of gold rings with blue topaz crafted in our own jewelry workshop.

How to choose the topaz of your ring

Maybe you did not know, but blue topaz can have different shades of blue.

As you can see in the above picture, blue topaz stone takes on different shades :

  • Sky blue topaz is sky blue
  • Topaz Swiss Blue is blue Caribbean

Regardless of the chosen stone's shape, you can also play on the blue shade of your topaz.

This gold ring pattern is a direct inspiration from our Izacalia ring design shown here.


Originally, this ring is set with a 4 millimeter princess cut diamond, but for our client, we have modified the design to fit a 6.5 millimeter stone size.

This modification allows it to have a bigger color stone for a much smaller budget than the same diamond ring design.

Gold manufacture

Once the ring design is adapted to our stone, a wax model is printed by 3D printing to make the ring size and stone assembly tests.

Follows the lost wax casting step, allowing us to get our 18-karat yellow gold ring from our wax model.

This thousand-year-old jewelry technique involves making a refractory plaster mold using our wax model, then destroying the model by heating the mold.

The molten gold is then poured into the mold and takes the form of the impression left free in the mold.

This video summarizes the steps of this process: 

We thus obtain our ring design in 18-karat gold, raw cast iron.

Metalwork then begins.

Our ring body is then deburred, and polished before mounting the stone in place.

For this other topaz ring project, this is a custom made yellow gold engagement ring.

If the budget for your engagement ring project allows it, this is surely the ideal solution to please. Simply choose the desired ring design and know your finger size to launch such a project.

In this case, it's an engagement ring drawn around a large stone of blue topaz carved in the shape of a pear.

The 18-karat yellow gold ring follows the tip of the topaz, which faces three small amethyst stones, also cut in the shape of a pear.

For this project, our client knew exactly what she wanted, so we started from the sketch she gave us.

Drawing, topaz ring blank to manufacture

Our client is not a professional in the jewelry sector and because jewelry design is a very demanding activity, we designed her ring project with our CAD tools.

And this in order to present a visual rendering faithful to what she could hope to expect once the ring is made.

Here is the rendering of this modeling.

Once the design is validated by our client, we can start manufacturing the 18-karat yellow gold ring by the lost wax casting process, following the same steps as for the ring's manufacture presented before.

Notice the raw look of gold and the claws that will be used to crimp the stones

Following this step, the finishing step begins with cutting the supply channels of our ring and polishing the gold.

Then comes the crimping of the stones to their respective locations.
