18k gold Scorpion ring
Scorpion is a symbolic animal, having its own constellation in the sky and its place in Greek mythology: Scorpius was ordered to kill Orion by Gaïa, the goddess of the Earth.
Symbol of desire and passion, it is an excellent subject for the making of zodiac-inspired jewels.
If we had the opportunity to make many animal-inspired jewelry, this is the first scorpion topic we had the opportunity to make.
It's a signet ring representing a scorpion in the sand with a 2,5 millimeters large HSI diamond on the tail and initials buried in the sand facing the scorpion. You will notice the details of the shell of the scorpion, the claws, its head the 7 paws (in spite of 8 as we worked this design from the 3D cad model from our client).

Be aware that this design is a unisez design, while showing of a very masculine style, this large ring which is 16 x16 millimeters was made for a woman, and can also be made for a man.
Below, you can discover other scropion jewelry, first is a white godl scorpion ring with a sapphire stone and then a silver scorpion pendant:
The creation of this ring project is divided into 4 stages :
- digital model
- 3D printing of the master of the ring
- white gold manufacture
- setting of the diamond and finishes
The digital model
Exceptionnaly, our client was already in possession of the CAD model of his project. Because of that, our work was greatly facilitated since we already had a working base for manufacturing process to take place.
As our client wanted his ring made in 18-karats white gold and gave us a weight limitation, we had to rework the CAD model to make it lighter. To do so, we carved the shank of the ring, making it hollow and saving gold weight to reach the aimed gold weight of 20 grams.
So, even if this ring was made for a woman, it is a pretty heavy piece of 18k gold jewelry.

3D printing of the resin ring
Once the digital model has been modified, it is possible to proceed to the manufacture of a wax master by 3D printing. This wax master was printed with 50 microns layers from an SLA printer using liquid castable resin.
This step allows us to produce a resin master 100% accurate according to the digital model, in every detail. This master will later be used to manufacture the casting modl used to make the metal ring.
Thanks to the master made previously, we manufacture a refractory plaster mold in which the molten white gold will be cast. Once the mold heated, the wax master is destroyed by sublimation and the empty footprint left in the mold can receive the liquid metal.
This video shows the steps of this process called : lost wax casting.
This way, we obtain our white gold scorpion ring as it appears raw cast.
Zoom on the raw foundry ring, we see perfectly the anatomical details of the scorpion and the location of the diamond
Diamond setting and finishes
After obtaining our gold cast ring, this latter is raw and need to be finished my hand. We can then go to finishing, polishing and setting the diamond at the level of the scorpion stinger.
Here is the first rendering after working to eliminate the burss and polishing the metal.

At this point, we can rhodium plate the ring to give it its bright white appearance.
