The aim of the project is to represent a train type TGV ring.
The creation of the ring begins therefore by taking into account the customer drawing and the picture of the reference train to be reproduced.
Sketch of the project and picture of the train to be made on the ring
The ring is made of a ring representing the rails on which a stylized TGV is mounted.
On the latter is set a lapis lazuli stone whose blue color is obviously reminiscent of the real train.
Making of the silver ring
The project begins with a 3D modeling phase that allows us to virtually sculpt the shapes of our ring project.
With the virtual photos of the digital model, we get this rendering, close to the future real rendering.

Once this design is validated by the project sponsor, we can launch the physical manufacture of the signet ring.
The 3D printing process allows us to physically obtain in resin our ring which was until now virtual.
The signet ring consists of two pieces, the ring-shaped rail and the train.
Then, by the lost-wax casting process, we make a refractory plaster mold in which the molten silver is then cast, thus allowing us to obtain the pieces of our silver ring.

The pieces are then deburred and then retouched and pre-polished before being assembled by soldering.
Welding of the silver ring parts
At this point, we can start the cutting work of lapis lazuli stone.
Cutting the lapis lazuli stone
For this big job, we start from a blog of raw lapis lazuli.
Three qualities of stones are possible, we will choose the best, the one presenting a deep blue with few incrustations of pyrites (on the left of the photo).
See 3 different grades of lapis lazuli stone with the best grade on the left
To cut the stone, we use a diamond disc mounted on micro motor and regularly cool the stone in water, which also serves as a lubricant for cutting.

The stone is cut and set in place.
Setting the stone on the men's silver ring
First cut the edges of the stone to ensure its fit in its location and then stick it in place.
Then we retouch the upper part by cutting and polishing successively to give it the desired curvature.
Finishing to cut the stone once set in place on the ring
Finishing the ring
The silver ring and the lapis lazuli stone are polished.

In order to bring out the details of the train, the ring is oxidized to blacken the silver.
The last polishing makes it possible to bring out the brilliance of the silver leaving only the blackened hollows, which makes it possible to appreciate at best the hollows and reliefs of the model of TGV.

Lapis lazuli gold ring with diamond
This next project is a lapis lazuli gold ring for women with a solitaire diamond set in the center of the lapis lazuli stone.
This is 6 grams 18k gold ring measuring 13 mm large with a 2 mm HSI white diamond on its center et flush.
The eagle is a mythological animal, used since the time of the Egyptians to symbolize the power of the gods or mysticism.
Chosen by the Romans, the Byzantines, Napoleon, the Russians empire or even the Nazis as an emblem to symbolize the power of their empire, the eagle, like the lion, is used in heraldry for family seals.
Even today, the eagle is used by the USA, Poland, and Mexico as an emblem of their nation.

Eagle signet ring using a family emblem
This is a ring we had the opportunity to make both in white and yellow 18k gold, as you can see.
For this project, we started from the emblem drawing of our client to make a 3D modeling of his eagle design on the plateau of the signet ring.

The reduction in size makes that one loses details of the drawing. To give an order of idea, the letters of the text will ultimately only a millimeter in height.
We also retouched the ends of the banner where the text is written to simplify the design which was not very visible once embossed.
We thus obtain a virtual sketch that allows us to have a good idea of the final rendering of our project.
Following this first phase, synthesizing the needs of the customer and what we can do in terms of details, the design is frozen to go into manufacturing workshop.
First, we print a wax master of the future ring which will then be used to make the mold in which the gold will be poured. We can see here drafts of the plate of the signet ring and realize the rendering of the engraving in relief of the drawing.
3D print tests of the signet ring top
You may notice that the engraved text remains readable despite the smallness of the letters.
Then we go to the actual manufacturing, we use our master to make a plaster mold in which is cast our molten gold.
here is the ring after the finishing process.

Double-headed gold ring with diamonds
This is a larger men eagle ring project featuring a double-headed eagle made of both white and yellow 18k gold.
This ring is much bigger, much heavier and set with 84 small diamonds and 1 main princess cut diamond on the top.
The making of a ring with a coin is a piece of classic jewelry.
Whatever the time or the country, there are relics or ancient gold or silver coin mounted on rings.
These coins can be mounted or crimped or be bent in order to partially compose the ring body.
Still today in France, many people custom made rings with gold coins called Louis d'or, or Napoléon coins that have historical value as well as pecuniary. While in the US, people are looking for eagle or Mexican gold coin to be mounted on a ring.

As we will see in this article, the project that follows, we describe the creation of a men's ring surmounted by a relief engraving taken from the coat of arms of Portugal present on a Portuguese coin struck in 1948.
Ring design from vintage gold coin
Our ring design is that of a simple signet ring topped with the embossed copy of the face of an old Portuguese coin.
This is a silver coin while the project of the ring is solid yellow 18k gold. Because it is not possible for us to mount the piece on the ring, we will have to reproduce the pattern.
We then use the computer tool to create a 3D modeling of the ring showing the engraving of the face of the piece by making a modification to the date of 1948 replaced by 1984.
Numeric model of the men's coin ring project
This virtual mock-up allows us to modify the source design at the same time and to ensure that the final rendering is fully in line with the expectations of the project sponsor.

Once the design is validated, we can start the physical manufacture of our ring by the 3D printing process to obtain a resin model of our ring.
Wax model of the coin ring before the casting process
Gold making of the ring
In possession of the resin physical model of our ring project, we can move to the lost wax casting stage.
A refractory plaster mold is created, containing our resin model. The latter is then burned out in order to sublimate the resin model which leaves a hollow space in the mold.
The molten yellow gold is then poured into the mold, the liquid gold then occupying the space left vacant by our resin model.
This video shows the steps of this process.

This process allows us to obtain our raw gold ring in accordance with the digital design and physical model obtained by 3D printing.
Gold coin ring after the casting process, note the rough state of gold
As you can see in this picture, we can see on the cast rough ring all the details of the coat of arms of Portugal visible on the reference coin shown at the beginning of the article.
Starts then the detailing process and the polishing of the ring and details of the engraving on the plate.

The engraving of his initials is a common and practical operation to personalize his signet ring.
These are the men who by far prefer the initial signs engraved with two or three letters on the board. This engraving can be done hollow or embossed on silver or gold.
When to make a gift, you are looking for a custom signet design different from the models of signet ring for men that we propose in our collection, the making of an engraved signet ring personalizes the jewel by making it unique.
Associated with the choice of the design of the signet ring and the decoration of the amounts of the ring, anyone can design his own signet ring of a unique style, as you can see through our articles presented at the end of this article.
We suggest you to discover different styles of initial signs made in silver or gold in our jewelry workshop.
Yellow gold is the most desired of the precious metal in jewelry, because of the heat of its glare, it has no equal.
Most family rings or signet rings are in 18-karat gold, but it is normal for exceptional jewels or signet rings that will remain for generations in the family to want a gold of the highest purity, of 24 karats.
Precision, 24-karat gold is necessarily yellow since it is not mixed with any other metal likely to change its color.
So there is no chance to find 24 karats white gold, pink or black gold. The only way to change 24k gold color if plating it with white or black rhodium.
24 karats gold nugget, check the color so characteristic of pure gold
Gold is usually mined mixed with other metals, so to obtain pure gold, rough godl nuggets are refined through an industrial process.
Miller's industrial process is the most widely used and it allows to obtain a 99.5% pure gold or a 23.88 karat gold.
Another process known as Wohwill since was set up in Canada, the latter allows to obtain a 99.999% pure gold (also called gold 5-9).
Legally in France, the pure gold title is given to bullion whose purity is at least 99.5% which is 23,88 karat once converted in karat purity grade.
Pure gold in jewelry
Pure gold is little used in jewelry for the manufacture of conventional jewelry.
Moreover, you will see that we do not find jewelry, rings, and chains in 24 karat gold in the trade for the reasons that we will detail below.
Jewelers produce pure gold when they refine gold from production waste.
Used gold bound to be refined, it comes in different colors and gold purity
Collecting gold for 10k, 14k or 18k, in different colors, it is advisable to reuse this gold to refine it to obtain a single pure gold ingot which can then be reused as needed to produce gold. 14k gold, 18k or 22k to choose.
Drawbacks of 24k gold for rings making
So why do not we find 24ct gold jewelry on sale in jewelers?
It's very simple, pure gold is capricious.
Although its reflections are seductive, it is extremely difficult to polish. While pure raw gold has a particularly bright reflection naturally, it is very difficult to get a good polishing of a ring or other jewel in 24-carat gold.
And if that were not enough, 24-karat gold is very malleable.
And so it folds and breaks easily for small sections of gold wire.
As a result, most of the fine and delicate designs of modern women's rings would not stand up to the abuse (bumps, scratches, and snags) that a classic ring experiences.
Only designs of simple rings or signet rings, massive, without fine parts or claws can bear to be made in 24 karat gold.
Thin gold ring damaged
Example of a 24 karat gold ring, you will notice the simple, massive design and the thick body to overcome the ductility of pure gold
The design of the ring includes a 3D sculpture of the logo on the square top of the ring and a deep engraving of initials in Gothic letters on each side of the ring uprights.
Our work begins with the realization of a 3D CAD model of the ring project that will validate the design with the sponsor. This step allows us to validate the dimensions, the volumes and the proportions of the different elements engraved with respect to each other.
It is at this stage that we really move from the project phase to a materialization of the future ring.
Numeric design of the men's biker ring
The advantage of the computer tool is that one can already have an idea of the final rendering of the ring even before its manufacture.
This permits us to avoid any design error between what our client wants and what we understand we have to make.
Rendering of the ring in sterling silver
Once the design is validated, we can then go to the actual manufacture of the ring.
First, a resin model is made with a 3D printer from the CAD file previously produced.
This resin ring will allow us to create a refractory plaster mold in which the molten silver will be poured in order to obtain our silver ring.

The ring is then deburred, the details retouched then the ring is polished and blackened to bring out the details of the design (the hollow letters and the dressing).
And gets this final result:
