The engagement being an important moment for the mutual engagement of the two partners of a couple, the modern tradition wants that the engagement ring is set with one or few diamonds.

Symbolizing eternity, the diamond is indeed the hardest and brightest stone of all precious stones and the most desired by women if we believe the current trend.

But adding a touch of personalization on her engagement ring is certainly an original detail, more economical than diamonds and will have a stronger and more lasting sentimental effect.

We will see during this article the steps of creating and making a custom engagement ring with the initials of the engaged couple.

This project differs from a previous project to create custom engagement ring that will interest you certainly (fr).

Did you know ?

The average budget of engagement rings in France is 700 euros, while in the US it's more than 5000 dollars.

Creation of the custom design

The design of the ring, created by the fiancé, is inspired by one of our ring designs from our engagement ring collection.

You can see below the design of the ring used for the modifications.

The fiancé wanted a rose gold body ring with modified white gold inserts and the removal of small brilliant diamonds set on the ring body.

The side inserts on the ring body have been replaced by the initials C and D above a heart-shaped pattern as shown in the following images.

As can be seen from the following detail, the ring is composed of 4 parts, namely :

  • the pink gold ring body
  • the two side inserts in white gold
  • the setting of the pink gold diamond

    Once the design is validated by the fiancé, we can begin the ring manufacture.

    Manufacture of the engagement ring 

    Manufacture begins with the 3D printing of a wax ring from the digital model of the project.

    View of the wax model with the ring body and one of the inserts, we note the perfect resemblance between the digital model and the printed parts 

    These resin-printed parts are then used as models to make a refractory plaster mold into which the molten gold will be cast.

    Of course, we will need for this ring to make a mold for the pink gold coins and another mold for the white gold coins.

    This process is called the lost wax casting process (because the wax model is destroyed in this process) and allows us to get our raw cast gold parts.

    At this point, we can then sanding our pieces to give them a good surface finish and remove their rough appearance and solder the white gold inserts to the ring body.

    This is a delicate and particularly rewarding manual operation. The picture shows the setting of the 0.11 carat diamond (3 millimeters in diameter).

    The ring is then polished and cleaned in an ultrasonic bath, giving us this final result :
