Au Goldsmiths started in Helsinki in 2003. We design and manufacture rings, earrings, necklaces and other jewelry from the very beginning of the process until the last finishing touches. We design timeless jewelry pieces and modern classics with passion. We love our work, and hope you can feel the commitment and love in our work too!


Au3 Goldsmiths is a collective of jewelry designers. Goldsmiths Tero Hannonen and Jussi Louesalmi started the company in 2003. The collective also includes goldsmiths Venla Metsola and Anu Kaartinen. Micromechanic Heini Viirto works at the Au3 workshop. We have many goldsmiths working for us through their own company. Store manager, goldsmith Essi Kyöstilä is in charge of the jewelry store at Unioninkatu 27, Helsinki, with the help of salesperson Marika Meriläinen who takes care of the Au3 Online shop. Photographer Julia Weckman is the head of marketing and visuals. You can contact us by email:

Ps. The wonderful illustration that we have on the wall of the jewelry store is made by the illustrator, artist Aino-Maija Metsola.



Precious metals and gemstones are valuable, so they should be carefully used and recycled as much as possible, especially from an ethical and ecological point of view. We renew old jewelry and use recycled materials whenever possible. All leftover material generated during the work is reused. The gold we use is always at least 99% recycled.

In our jewelry we mainly use gold and platinum, but also other materials such as silver. We use diamonds, sapphires and other durable and high-quality gems.

We acquire gemstones from our reliable long-term material suppliers and partners. We only use diamonds from legal sources and producers who are committed to the Kimberley International Agreement. We provide a certificate of authenticity for the materials and for the jewelry designed and manufactured by us at Au Goldsmiths.


We at Au3 Goldsmiths mostly use gold and platinum, with gems like diamonds and sapphires. Read more about materials and find out how to take care of them!
