Look closely at an antique silver pendant and you may find the metal has been worked into something that resembles lace — curls, scrolls and tiny beads with air between them. That technique has a name, and the question comes up often enough to deserve a proper answer: what is filigree? It is a method of building jewellery from fine twisted wire, shaped into open patterns and joined by soldering, so the finished piece is as much empty space as metal.
What is filigree, in plain terms?
The maker starts with very thin wire, usually silver or gold. Two strands are twisted together and then flattened slightly, which gives the wire a grained, rope-like edge that catches the light. Those wires are bent into curls, spirals, teardrops and scrolls, laid out inside a frame, and soldered where they touch. Granulation — tiny metal spheres fused onto the surface — is often used alongside it.
The defining feature is openness. Solid metal with a pattern cut into it is pierced work, not filigree. Real filigree lets light through the gaps, which is why it looks so much lighter than it should for its size.
Where it comes from
Filigree is genuinely ancient. Examples survive from Mesopotamia and Ancient Egypt, and the technique travelled widely — to Etruscan Italy, to the Iberian peninsula, to India, to the Malay archipelago and across the Andes. Several regions still have living traditions associated with it, including Portugal, Malta, Oman and parts of Indonesia.
Western jewellery had a major filigree revival in the early twentieth century, when Edwardian and Art Deco makers used it heavily for engagement rings and brooches. Those pieces are the ones most often found in antique shops today.
Filigree, pierced work and stamped imitation
Three different things get sold under the same word, and telling them apart is useful.
- True filigree is built up from individual wires. Look under magnification for the twist in the wire and for the small solder joins where strands meet.
- Pierced or sawn work starts as a sheet of metal with the pattern cut out. The edges are smooth and flat, with no wire texture.
- Cast or stamped imitation is a mould-made copy of a filigree original. It has the look but the detail is softened, the reverse is usually flat, and the whole piece feels heavier than genuine wirework.
Getting a filigree look without a soldering bench
Traditional filigree needs drawn wire, a solder setup and a lot of practice. There is a gentler route to a similar effect, which is to build the openwork in silver clay before firing rather than soldering it afterwards. Extruded or rolled coils of clay can be arranged into scrolls and joined with paste while everything is still soft, so the joins happen at the clay stage instead of with a torch and solder.
A few things worth knowing if you try it. Thin elements dry quickly and become fragile before firing, so support them and handle the piece as little as possible while it is bone dry. Joins want to be genuinely wet with paste, not just pressed together. And because silver clay shrinks by around 8–10% as it fires, gaps close up a little — leave your spaces slightly wider than you want them to end up. What comes out of the flame is 99.9% fine silver.

Caring for filigree pieces
Openwork is delicate by design, and it collects dust and polish residue in exactly the places you cannot reach. Use a soft brush rather than a cloth, since cloth fibres snag on the wires. Avoid ultrasonic cleaners with antique filigree, because old solder joins and any set stones may not survive the vibration. Store pieces separately so nothing hooks through the gaps, and keep them out of pockets and bag linings where a single catch can bend a scroll out of shape.
Bent filigree can often be eased back with patience, but a broken wire needs a jeweller. It is worth the care: few techniques give so much presence for so little metal.
