Tanzanite stone, although not listed as a precious stone, is a mesmerizing stone, not only because of its recent discovery by casualty but also because of its deep blue reflections.

Our client chose yellow gold for his Tanzanite ring.

This tanzanite ring is made from one of our own signet ring design on which has been set a large cabochon tanzanite stone fitting our client's requirement.

This kind of customization is available through our custom making service online.

Ring's design

This ring is made by taking the design of one of the signet rings of our collection and replacing the onyx stone faceted by a big tanzanite cabochon.

The design of this ring was therefore adapted to crimp on the ring a stone as big, making 14.1 x 10 millimeters, or 8.6 carats.

Here is what gives the first sketches of this ring design with such a tanzanite cabochon:

The design of the ring gives us a good rendering of the volume occupied by the cabochon stone, while the rendering below allows us to see the rendering of the colors.

Once the design is validated by the customer, we can proceed to the actual manufacture of the ring.

Gold ring making

We start the making by 3D printing the master model of the ring. This model will then be used to cast the ring in gold with all its details.

Lost wax casting process allows us to get our gold ring from the wax ring model we had 3D printed previously.

You can check the septs of this process with this video:

You can see below our raw gold foundry ring at the end of the casting process.

A first blank test of tanzanite in its housing allows us to see the adjustments to be made and note the development of tanzanite in cabochon on the ring.

We are not sure if this is the ring that highlights the stone or the tanzanite that will highlight the gold ring.

This exceptional stone cannot leave indifferent. Discovered in the 60s and still little known to the general public, it has already made a splash in the world of jewelry.

It has a deep blue color and color variations from red to purple when the stone is cut into facets.

Its blue color is well worth that of some sapphire while being more affordable than these.

We had to add a gold sheet inside the ring to close the inner ring body.

Then the ring can be set with 2 diamonds and tanzanite stone before final polishing.

We can then appreciate the final rendering of the ring and the blue chips of tanzanite.
