about the
label.

21-12 is a contemporary jewellery label based in Antwerp, Belgium. We try to find a balance between the ancient craftsmanship of goldsmithing and innovative techniques and materials. This results in a progressive collection of sustainable elegant jewellery.

about the
designer.

Jewellery designer Tine Sibbens first discovered the techniques of goldsmithing in 2007 at the Royal Academy of Fine Arts in Antwerp. She further developed these skills at the Academy of Fine Arts in Sint-Niklaas where she graduated in 2014. She combined this extensive education with several technical courses where she discovered the use of innovative materials.

we are
sustainable.

We use precious metal and vegetal tanned leather of the highest quality and combine these natural materials with innovative new ones, such as advanced plastics. The quality of the materials is very important for us and therefore we use only the best materials.
