Niello is a black inlay used to decorate engraved silver and gold. A mixture of silver, copper and lead sulphides is melted into lines cut into the metal, then filed and polished flat, so the design shows in deep black against the bright metal. The name comes from the Latin nigellus, "blackish". Niello was used from Roman times to the 1900s, and it is best known today on Russian and Caucasian silver.

What is niello made of?
Niello is a mixture of metal sulphides: silver, copper and lead melted together with sulphur, then cooled and ground to a black powder. It is a metallic compound, not a paint and not an enamel, and it bonds to the metal around it. The exact recipe changed between periods and workshops.
How is niello applied?
- The design is cut into the silver or gold by engraving, chasing or etching.
- Niello powder is packed into the recesses, usually with a flux.
- The piece is heated until the niello melts and flows into every line.
- The surface is filed and polished flat, so only the black-filled design remains.
The result is a sharp black drawing set into the metal, smooth to the touch.
A short history of niello
- The ancient world. Roman silversmiths used niello on silver plate, jewellery and fittings.
- Anglo-Saxon England. Brooches and fittings of silver and niello, such as the 9th-century Fuller Brooch in the British Museum.
- Medieval and Byzantine Europe. Niello appears on church plate, crosses, rings and reliquaries.
- Renaissance Florence. Goldsmiths engraved and nielloed silver plaques; prints taken from these plates, called nielli, are among the early steps towards engraved prints.
- Russia and the Caucasus. From the 1700s Russian silversmiths, notably in Veliky Ustyug and Moscow, made snuff boxes, beakers, cigarette cases and spoons with niello views, maps and scrolls. Caucasian and Armenian workshops used niello on belts, buckles and daggers.
- Southeast Asia. Siam (Thailand) produced nielloware silver in the 1900s.

How to recognise niello
0 of 4 checked
1The colour
A dense, slightly metallic black, not a painted or lacquered black.
2The surface
Flush with the metal; you cannot feel the edge of the black.
3The marks
Russian silver usually carries a town mark, an assayer’s mark, a maker’s mark and a silver standard such as 84; Armenian and Caucasian pieces may carry Russian marks too.
4The style
Russian pieces often show city views, maps or scrolling foliage; Siamese pieces often show dancers and figures from legend.

How to care for niello
Niello is brittle. Do not heat it, use an ultrasonic cleaner or drop the piece: the black can crack or fall out. Clean with a soft cloth and only a mild silver polish on the metal around it. Losses can be refilled by a specialist restorer.
What makes niello silver valuable?
The maker and marks, the age, the quality of the engraving and the niello, the subject (views and maps are sought after), the condition of the niello and the provenance. We never publish figures; every piece is different.
