Portal Jewellery is a design studio based in London.

Jewellery designers Di Ananieva and Björn Altmann combine their talents to create futuristic 3D-modelled pieces in sterling silver and gemstones. The inspiration came from a common interest: mythology and fairy tales. Pathways that can only be found once, a door that only opens if you have deciphered the code, hidden portals to another world - all of these exciting ideas formed the starting point for the designs.

Di and Björn are independent designers who have both participated in Milano Jewellery Week 2022. Di has also exhibited at Venice Design Week 2023 and others and is a GIA graduate gemologist. Björn also works with luxury watch brands.
