How Is Sardinian Filigree Jewelry Made?
Sardinian filigree jewelry is made by working with extremely fine gold or silver wires, which are twisted, curved, shaped, and soldered together to create highly detailed ornamental patterns.
The manufacturing process involves several stages: preparing the metal, creating the wires, building the structure of the jewel, shaping the filigree, soldering the individual elements, refining the piece, and carrying out the final polishing.
In traditional handcrafted filigree, many of these operations are performed manually and require precision, experience, and careful temperature control during soldering.
The Region of Sardinia also officially distinguishes between two main types of filigree work: “a giorno”, in which the pattern is built inside a structure without a solid backing, and “a notte” or “a buio”, in which the wires are applied over a metal support. (regione.sardegna.it)
Let’s look step by step at how a Sardinian filigree jewel is made.
How Is Sardinian Filigree Made? The Short Answer
The process can be summarized in these stages:
preparation of the gold or silver;
transformation of the metal into very fine wires;
possible twisting of two or more wires;
construction of the jewel’s structure;
shaping the wires into spirals, curves, and ornamental motifs;
inserting the filigree into the structure;
soldering the contact points;
adding granules or other decorative elements;
cleaning and finishing;
final polishing.
The result can be a ring, a Fede Sarda, an earring, a pendant, a Bottone Sardo, a bracelet, or another traditional Sardinian jewel.
You can see several examples in the Gioia Sarda handcrafted Sardinian jewelry collection.
What Exactly Is Filigree?
Filigree is a goldsmithing technique based on working with extremely fine metal wires.
According to the definition provided by the Treccani Encyclopedia, the technique essentially consists of bending and intertwining fine strands of precious metal and joining them at the points of contact through soldering. (treccani.it)
Filigree can be made using both gold and silver.
What makes it immediately recognizable is its light and highly detailed appearance, created through:
wires;
spirals;
curves;
interwoven patterns;
small granules;
geometric elements;
floral motifs;
openwork structures.
The very word “filigree” refers to the combination of thread and grain, two elements that have historically characterized this type of goldsmithing. (treccani.it)
1. It Starts with the Metal
The first stage consists of preparing the precious metal.
Depending on the jewel, either gold or silver can be used.
Many Gioia Sarda jewels are made using certified TIT.800 silver.
800 silver is an alloy containing 80% silver, while the remaining percentage consists of other metals that give the alloy properties suitable for working.

2. The Metal Is Drawn into Extremely Fine Wires
To create filigree, the metal must be transformed into very fine wires.
In modern goldsmithing, this process can be carried out using a drawplate, a tool with progressively smaller holes through which the metal wire is pulled.
With each pass, the wire becomes thinner.
Treccani describes the modern process as one in which the metal passes through perforated plates until the desired thickness is reached. (treccani.it)
Precision is essential at this stage.
A wire that is too thick would make the design look heavy, while an extremely thin wire could be more difficult to shape and solder.
3. The Wires Can Be Twisted
One of the characteristic features of many filigree techniques is the use of twisted wires.
Two extremely fine wires can be placed together and wrapped around one another until they form a structure that resembles a tiny rope.
This creates a richer and more decorative surface compared with a simple smooth wire.
Documentation from the Region of Sardinia also describes filigree as a technique involving the intertwining and bending of thin, smooth or twisted wires, which are then joined by soldering. (regione.sardegna.it)
4. The Structure of the Jewel Is Built
Before filling the jewel with filigree motifs, it is often necessary to create an outer structure.
In technical language, this structure may be referred to as the “scafo.”
It acts like a frame that determines:
shape;
size;
proportions;
outline of the jewel.
It can be circular, oval, floral, geometric, or take on more elaborate forms.
The worked wires are later inserted inside this structure.
5. The Wires Are Shaped One by One
This is one of the most characteristic stages of filigree work.
The wire is:
curved;
wrapped;
bent;
rolled;
flattened;
arranged into small motifs.
This can create:
spirals;
scrolls;
floral motifs;
geometric shapes;
small curls;
symmetrical compositions.
The artisan needs to prepare elements that are similar enough to create visual harmony while still adapting them manually to the structure of the jewel.
This is one of the reasons why handcrafted filigree requires so much precision.
6. What Is “A Giorno” Filigree?
“A giorno” filigree is one of the most important techniques.
According to the regulations of the Region of Sardinia, it is created without a solid backing behind the jewel.
First, the outer structure is built. It is then filled with worked wire, which is soldered at the points where it comes into contact with the structure. (regione.sardegna.it)
The result is the typical sense of lightness and transparency that characterizes many filigree jewels.
When looking through the jewel, you can see the spaces left between one wire and another.
This technique is particularly suitable for:
earrings;
pendants;
brooches;
buttons;
decorative elements.
7. What Is “A Notte” or “A Buio” Filigree?
The second technique identified in the regional regulations is “a notte” or “a buio.”
In this case, a metal surface is used as a support.
The twisted and shaped wires are arranged and soldered directly onto this base. (regione.sardegna.it)
Unlike “a giorno” filigree, you cannot see through the motif.
The decoration is built on top of a solid metal surface.
The two techniques allow for very different visual effects and can be used depending on the type of jewel being created.
8. How Are the Filigree Wires Soldered?
Once the individual elements have been positioned correctly, they need to be fixed in place.
This is done through soldering.
The contact points are joined using soldering material and controlled heat.
This is an extremely delicate stage.
Insufficient heat may fail to secure the elements properly.
Excessive heat, on the other hand, could:
deform the wires;
melt very small details;
alter the structure;
compromise the design.
Treccani describes filigree precisely as a technique in which thin metal strands are joined through soldering at their contact points. (treccani.it)
9. What Are the Small Granules on Sardinian Jewelry?
Many Sardinian jewels also feature small metal spheres.
This decorative technique is called granulation.
Filigree and granulation are different techniques, but they can be used together.
Treccani clearly distinguishes filigree, which is mainly based on working with wires, from granulation, which uses tiny metal grains or spheres. (treccani.it)
These small elements are particularly important in Sardinian jewelry.
In the Fede Sarda, for example, the tiny spheres traditionally resemble grains of wheat and are associated with prosperity.
The official SardegnaTurismo website also describes the Fede Sarda as a jewel made by joining tiny spheres reminiscent of wheat grains. (sardegnaturismo.it)
You can see different examples in the collection of Fedi Sarde and Fedine.
10. The Soldering Is Checked and Refined
After soldering, the jewel must be inspected carefully.
The artisan checks that:
all wires are properly secured;
the structure is not deformed;
no elements are sticking out;
the composition is balanced;
the soldering does not compromise the design.
Further manual corrections may be made at this stage.
Filigree is a technique in which even a few millimeters can noticeably affect the symmetry of the final result.
11. The Jewel Is Cleaned
During the working and soldering process, residues and traces of production can remain on the surface.
The jewel is therefore cleaned through specific workshop procedures.
This stage prepares the metal for the final finishing process and makes the small filigree details clearly visible again.
12. The Filigree Is Polished
The final main stage is polishing.
The regulations of the Region of Sardinia explicitly state that, after working, gold or silver filigree is polished in order to remove the remaining dullness of the metal. (regione.sardegna.it)
However, polishing must respect the structure of the jewel.
Very fine filigree cannot be treated with the same intensity as a completely smooth metal surface.
The goal is to give the metal brightness without losing definition in the details.
How Long Does It Take to Make a Sardinian Filigree Jewel?
There is no single standard time.
It depends on:
size;
complexity;
amount of filigree;
number of elements;
number of soldering points;
presence of granules;
any stones used;
final finish.
A simple model naturally requires less work than a jewel made up of a large number of wires and details.
For this reason, the time required should not be judged solely by the size of the jewel.
A small but highly elaborate pendant may still require very precise work.
Is Sardinian Filigree Handmade?
In traditional handcrafted filigree, the main stages of composition and assembly are carried out manually.
The regional regulations for “Filigrana artigiana - SARDEGNA” explicitly require that products complying with those regulations and using the relevant collective mark indicate that the product has been made “entirely by hand.” (regione.sardegna.it)
This does not mean, however, that every product generically described online as “Sardinian filigree” automatically falls under those regulations or uses that mark.
For this reason, it is always important to check the information provided by the individual maker or seller.
How Long Has Filigree Existed in Sardinia?
The tradition is very old.
The official SardegnaTurismo website connects modern-day craftsmanship with ancient jewelry discovered at Sardinian archaeological sites such as Karalis, Nora, Neapolis, and Tharros, highlighting how the technique has been passed down through the centuries. (sardegnaturismo.it)
Filigree did not originate exclusively in Sardinia.
It is an ancient goldsmithing technique documented across different civilizations of the Mediterranean and the Near East. Treccani mentions ancient examples in Egypt, the Aegean world, and other archaeological contexts. (treccani.it)
In Sardinia, however, the technique developed forms, symbols, and uses that are strongly connected with local culture.
Which Jewelry Is Made Using Sardinian Filigree?
The technique can be used for many different types of jewelry.
Among the best known are:
Fedi and Fedine Sarde
These are among the most recognizable symbols of Sardinian goldsmithing tradition.
You can explore the collection of Sardinian rings, Fedi and Fedine.
Earrings
Filigree makes it possible to create lightweight earrings even when the design is particularly elaborate.
You can explore the Sardinian filigree earrings.
Pendants
The openwork structure of filigree is particularly well suited to pendants.
You can see the pendants and Bottoni Sardi.
Bottoni Sardi
The Bottone Sardo is one of the most characteristic elements of traditional Sardinian clothing and jewelry.
You can learn more in the guide dedicated to the Bottone Sardo.
Bracelets and Charms
The technique is also used for smaller elements that can be incorporated into bracelets and more contemporary compositions.
You can explore the Sardinian bracelets and charms.
Why Is Sardinian Filigree So Recognizable?
Sardinian filigree stands out not only because of the technique itself, but also because of the way it became integrated into the island’s culture.
Traditional jewelry accompanied:
traditional clothing and costumes;
weddings;
engagements and promises;
religious occasions;
family events;
symbols of protection;
community identity.
SardegnaTurismo explains that necklaces, pendants, chains, earrings, brooches, buttons, and amulets were part of traditional costumes and that each jewel could express the identity of a particular community. (sardegnaturismo.it)
For this reason, talking about Sardinian filigree means talking both about goldsmithing technique and cultural heritage.
Are Filigree and Industrial Production the Same Thing?
No.
A decoration can visually imitate filigree without actually being made through the traditional process of working with fine metal wires.
For this reason, when looking for handcrafted jewelry, it is useful to check:
whether close-up details are shown;
whether the workmanship is explained;
which material is used;
whether the product is described as handcrafted;
who makes it;
whether clear information about origin is provided.
You can learn more in the guide How to Recognize Authentic Handcrafted Jewelry.
How Can You Tell If Filigree Is Well Made?
Pay particular attention to:
Element | What to Check |
Wires | Thin and clearly defined |
Interwoven details | Neat and harmonious |
Soldering | Visually discreet |
Symmetry | Balanced in relation to the design |
Granules | Properly positioned |
Structure | Solid without appearing heavy |
Finish | Even and carefully executed |
Details | Clearly visible |
A handcrafted jewel does not necessarily need to look identical to an industrially stamped product.
Small variations can be compatible with manual craftsmanship.
However, they should not be confused with structural defects or poor workmanship.
How Should Filigree Be Cared for After Purchase?
Precisely because it is made up of wires and small details, filigree should be handled gently.
In general, it is advisable to:
avoid knocks;
not pull on the wires;
keep it away from harsh cleaning products;
avoid rubbing it with abrasive materials;
store it separately from other jewelry;
dry it thoroughly before putting it away.
