What filigree actually is
Filigree is lace made of metal. The technique takes very fine threads of gold or silver, often twisted together into a beaded rope thinner than a hair, and shapes, curls and solders them into open, airy patterns held together with almost no solid backing. The result is jewellery that looks impossibly delicate, full of tiny loops, scrolls, hearts and flowers, yet is strong enough to wear. The word comes from the Latin filum, thread, and granum, grain, describing exactly the two elements of the craft, the drawn wire and the tiny granules that decorate it. It is one of the oldest forms of goldsmithing in the world.
In Portugal, filigrana is a living tradition rather than a museum piece, still made by hand by goldsmiths who spend years learning to control thread that a breath could bend. Machines can imitate the look, but true filigree is assembled piece by piece under a magnifying lamp, which is why it commands the price it does. Understanding this at the outset changes how you shop, because it explains why a real gold heart costs what it costs and why the identical-looking two-euro pendant on a market stall cannot possibly be the same thing.
Filigree is a headline entry in my guide to Portuguese traditional clothing, because the jewellery and the costume belong together.
The Coracao de Viana, Portugal's famous heart
The single most recognisable piece of Portuguese filigree is the Coracao de Viana, the heart of Viana. It is an ornate golden heart, usually shown either crowned or wreathed in flames rising from its top, worked in fine filigree and hung from a ribbon or chain. The flaming version carries a devotional meaning, associated with the Sacred Heart, while the whole object has become a symbol of love, of the Viana do Castelo region, and increasingly of Portugal itself. You will see it everywhere from festival costumes to modern fashion, scaled from tiny pendants to hearts the size of a fist.
The heart belongs to the folk dress of the Minho, and this is the key to understanding it. In the great romarias, the religious festivals of the north, women of Viana traditionally wore layers of gold, hearts, huge earrings, chains and crosses, over their embroidered costume, a display of family wealth and regional pride literally worn on the body. The Coracao de Viana was the centrepiece of that display. So when you buy one, you are buying a fragment of a specific and vivid tradition, not a generic love token, which is exactly why it deserves its place both here and in my traditional clothing guide.
Where filigree is made, Gondomar and Povoa de Lanhoso
Portuguese filigree has a geography, and it is worth knowing before you buy. The historic capital of the craft is Gondomar, a town on the edge of Porto, where goldsmithing has been the dominant trade for generations and where most of the country's gold filigree is still made by hand today. If a Portuguese person tells you their filigree is from Gondomar, they are telling you it comes from the source. The town's workshops supply jewellers across the country, and Gondomar gold has a reputation the way a wine region has a name.
The second great centre is Povoa de Lanhoso, in the Minho near Braga, which has its own deep filigree tradition and even a dedicated museum of the craft where you can see the tools, the history and the finest antique pieces. Between Gondomar and Povoa de Lanhoso, the north of Portugal holds almost the entire tradition, which is no accident, since the Minho is also the home of the folk costume the jewellery was made to adorn. Buying filigree in the north, close to where it is made, gives you the best selection and the most knowledgeable sellers, the same source-buying logic that runs through my what to buy in Portugal guide.
How filigree is made by hand
Watching filigree being made explains its value instantly. The goldsmith starts by drawing the metal into extremely fine wire, then twists two strands together and flattens them slightly into a beaded ribbon, the basic thread of the craft. Using tweezers under a magnifying lamp, they bend and coil this thread into the tiny scrolls and shapes of the design, laying them into an outline frame like filling in the cells of a stained-glass window with metal lace. Everything is held in place with a fine solder that must flow at exactly the right heat, because a fraction too much and the delicate threads melt away entirely.
The finest work then adds granulation, minute grains of gold fused onto the surface for texture, and the piece is cleaned and polished to bring up the shine. A single elaborate heart or pair of festival earrings can take many hours of this close, painstaking handwork, which is why no machine-made copy ever quite matches it. This is also how you understand quality: the real thing shows crisp, even, hand-laid threads and secure joins, while a cheap cast imitation has soft, blurred detail because it was poured into a mould rather than built from wire. Knowing the process is the best defence against paying gold prices for a copy.
Gold or silver, and Portugal's 19.2 carat standard
Filigree comes in two metals, and the choice shapes both meaning and price. Traditional festival filigree, the grand hearts and earrings of the Minho, is gold, and Portuguese gold has its own standard: 19.2 carat, equal to 800 parts of gold per thousand, a purity specific to Portugal and warmer in colour than the 18 carat common elsewhere. A large gold Coracao de Viana is a serious purchase, priced by the weight of gold plus the labour, which is why the grandest antique pieces are genuine family treasures handed down through generations.
Silver filigree is the accessible everyday alternative, and it is what most visitors actually buy. It uses the identical technique and the same lace-like designs, including small Viana hearts, earrings and pendants, but at a fraction of the cost of gold, which puts real handmade filigree within easy reach. There is nothing second-rate about silver filigree, it is simply the democratic version of the craft, and a well-made silver heart is a lovely, authentic thing to own or give. Whether you go gold or silver, the important line is not between the two metals but between solid precious metal and cheap plated imitation, which the next section explains.
How to spot real filigree from plated copies
The market is full of cheap copies, and telling them apart protects your money. The single most reliable check is the hallmark. Genuine Portuguese gold and silver must be stamped with an official assay mark, the contraste, applied by the state assay office to certify the metal and its purity, so real filigree carries tiny official stamps you can find with a loupe. A piece with no hallmark, sold at a suspiciously low price, is almost certainly plated base metal dressed up to look like the real thing. Ask the seller to show you the mark, and a reputable goldsmith will do so happily.
Beyond the stamp, look at the work and the price. Real filigree shows crisp, individually laid threads and clean solder joins under close inspection, while a cast copy has soft, blurred, uniform detail because it was moulded, not built. Weight and price also tell: solid gold is heavy and expensive, and anything claiming to be a gold Viana heart for a handful of euros is a fake. Buy from an established jeweller or goldsmith rather than a street stall, keep the receipt and any certificate, and you remove almost all the risk.
This is the same buyer discipline, provenance, hallmark, honest price, that I apply to every craft in my made in Portugal guide.
What filigree means in Portuguese culture
Filigree is not just decoration in Portugal, it is bound up with love, faith and family. The Viana heart is a traditional token of affection and betrothal, given between sweethearts and worn at weddings, and the gold a bride wore was often her portable wealth and security, jewellery she owned outright in an age when women owned little else. Passed from mother to daughter, these pieces carry generations of a family in their threads, which is why so many Portuguese people, myself included, own a heart or a pair of earrings that came to them from a grandmother rather than a shop.
The jewellery also anchors the great folk festivals of the north. At the romarias, above all the Romaria de Nossa Senhora da Agonia in Viana do Castelo each August, women still process in full Minho costume weighed down with gold filigree, a living display of a tradition centuries old. Seeing it worn as intended, on real people at a real festival rather than in a shop window, is the best way to understand why the craft survives. It is a thread that ties the folk costume, the family and the region together, and it belongs in any honest picture of Portuguese culture and traditions.
Where to buy filigree and what to pay
For the real thing, buy from an established goldsmith or jeweller, ideally in the north where the craft lives. Porto and its neighbour Gondomar have the densest concentration of genuine filigree jewellers, and towns across the Minho, including Viana do Castelo and Povoa de Lanhoso, sell it close to the source. Reputable shops in Lisbon carry it too. Wherever you buy, ask about the metal, look for the hallmark, and favour a seller who can tell you where and how the piece was made. The knowledgeable sellers cluster where the tradition is strongest.
On price, small silver filigree such as stud earrings or a little heart pendant starts around 30 to 60 euros, larger and more elaborate silver pieces climb into the low hundreds, and gold filigree is priced by weight and labour, with a proper gold Coracao de Viana running from several hundred to several thousand euros depending on size. That range means there is genuine handmade filigree for almost any budget, as long as you buy solid metal rather than plating. A small silver heart is an affordable, authentic keepsake; a gold one is an heirloom.
Either way it is among the most meaningful things you can carry out of Portugal, which is why I rank it so highly in my Portugal souvenirs guide.
Why it matters
Why it matters: the Coracao de Viana is one of Portugal's most recognisable symbols, but the pretty hearts in tourist windows range from genuine handmade gold to cheap plated fakes, and most visitors cannot tell the difference. Understanding that filigree is a centuries-old craft centred on Gondomar and the Minho, that real pieces are solid gold or silver carrying an official hallmark, and that the heart is tied to folk costume, love and family, turns a risky souvenir into a meaningful and lasting one. Knowing to check the contraste stamp and to buy from a real goldsmith is the difference between owning an heirloom and owning a fake.
Practical tips
- Check for the official Portuguese hallmark, the contraste, stamped on any real gold or silver filigree; no hallmark plus a low price means plated base metal.
- Buy from an established goldsmith or jeweller, ideally in the north around Porto and Gondomar or in the Minho, rather than from a street stall.
- Choose silver filigree for an affordable authentic piece from around 30 to 60 euros, or 19.2 carat gold for a heirloom heart priced by weight and work.
- Inspect the threads under close light: real filigree shows crisp, individually laid wires and clean joins, while a cast copy looks soft and blurred.
- Time a northern trip for the Romaria da Agonia in Viana do Castelo each August to see gold filigree worn with full Minho costume as it was meant to be.
Local insight
Local insight: my advice to anyone who wants a Coracao de Viana is to decide honestly whether you want a keepsake or an heirloom, because the two are bought completely differently. If it is a keepsake, buy a small solid silver heart from a proper goldsmith for a modest price, check the hallmark, and enjoy owning the real craft without spending a fortune. If it is an heirloom, go to the north, to Porto or the Minho, spend time with a jeweller, and buy gold by weight from someone who can tell you exactly where it was made.
The one thing I always talk people out of is paying gold-heart prices for an unhallmarked stall piece, which is neither keepsake nor heirloom, just a fake.

Frequently Asked Questions
What is Portuguese filigree?
Portuguese filigree, filigrana, is jewellery made by hand from very fine threads of gold or silver, twisted and soldered into delicate openwork patterns that look like lace made of metal. The technique is centuries old and concentrated in the north of Portugal, above all in Gondomar near Porto and Povoa de Lanhoso near Braga. Its most famous product is the Coracao de Viana, the ornate Viana heart worn with the traditional folk costume of the Minho. Real filigree is solid gold, traditionally 19.2 carat, or solid silver, and carries an official Portuguese hallmark. It is a living craft, still assembled thread by thread under a magnifying lamp.
What is the Coracao de Viana?
The Coracao de Viana, the heart of Viana, is the most recognisable piece of Portuguese filigree, an ornate golden heart usually shown crowned or wreathed in rising flames and worked in fine gold or silver thread. The flaming form is linked to the Sacred Heart and carries a devotional meaning, while the heart as a whole symbolises love and has become an emblem of the Viana do Castelo region and of Portugal itself. It belongs to the folk dress of the Minho, where women traditionally wore layers of gold filigree over their costumes at the great religious festivals.
Today it appears everywhere from festival dress to modern fashion, in sizes from tiny pendants to fist-sized hearts.
How can I tell real filigree from a fake?
The most reliable check is the hallmark. Genuine Portuguese gold and silver must carry an official assay stamp, the contraste, certifying the metal, so real filigree has tiny official marks you can find with a loupe. A piece with no hallmark sold at a very low price is almost certainly plated base metal. Beyond the stamp, look at the work: real filigree shows crisp, individually laid threads and clean solder joins, while a cast copy has soft, blurred, uniform detail because it was moulded rather than built from wire. Solid gold is also heavy and expensive, so a gold Viana heart offered for a few euros is a fake.
Buy from an established goldsmith and ask to see the mark.
Where is filigree made in Portugal?
Portuguese filigree is made almost entirely in the north. The historic capital of the craft is Gondomar, on the edge of Porto, where goldsmithing has been the main trade for generations and where most of the country's gold filigree is still handmade today. The second great centre is Povoa de Lanhoso, in the Minho near Braga, which has its own deep tradition and a dedicated filigree museum. This northern concentration is no accident, since the Minho is also the home of the folk costume that the jewellery was made to adorn. Buying filigree in the north, close to the source, gives you the widest choice and the most knowledgeable sellers.
How much does Portuguese filigree cost?
It spans a wide range depending on metal and size. Small silver filigree such as stud earrings or a little heart pendant starts around 30 to 60 euros, and larger, more elaborate silver pieces climb into the low hundreds. Gold filigree is priced by the weight of the gold plus the hours of handwork, so a proper 19.2 carat gold Coracao de Viana runs from several hundred to several thousand euros depending on its size. That means there is genuine handmade filigree for almost any budget, as long as you buy solid gold or silver rather than plated imitation.
A small silver heart is an affordable authentic keepsake, while a gold one is a true heirloom.
What does 19.2 carat gold mean in Portugal?
19.2 carat is the traditional Portuguese gold standard, equal to 800 parts of pure gold per thousand, and it is specific to Portugal rather than the 18 carat common in much of Europe. It gives Portuguese gold a slightly warmer colour and is the purity in which traditional filigree, including the grand Viana hearts and festival earrings, is usually made. Portuguese law requires precious metals to be tested and hallmarked by the state assay office, so genuine 19.2 carat gold carries an official stamp certifying its purity.
When buying gold filigree, this hallmark is your guarantee that you are getting solid Portuguese gold at the stated standard rather than a lower-grade alloy or a plated copy.
