Get in touch ↗OUR STORYFour generations.
Four generations.
The same dedication to jewellery.
The story of JBC began long before its name. We are the great-grandchildren of goldsmiths, inheriting skills passed down through generations at the workbench, in shaping metal and in the care given to every piece.
Our journey includes a company with a long history in Portuguese jewellery manufacturing, founded in 1985. It was in that environment of production and learning that we developed the experience we bring to JBC today.
Now, a new generation carries that story forward. We preserve the knowledge and dedication of those who came before us, combining them with technologies and processes that open up new possibilities in manufacturing.
Generations change. Our commitment to jewellery endures.
