Gad Leinson

​

Ever since he was a small boy Gad Leinson’s passion has been to build miniature models. Fired by this passion he always knew that he wanted to become a goldsmith by profession.

After school Gad became an apprentice at a goldsmith's workshop in Helsinki. Knowing exactly what he wanted  he set his sights to Israel, where the secrets of goldsmiths have been handed down from father to son for many generations.

He then studied intensively for one year in Jaffa. As a talented student, Gad made an impression and he was granted an apprenticeship to join the workshop of the world famous Viktor Naaman in Tel Aviv. Furthermore, as a result of Gad’s resilience, determination and steadfast studying he had the honour to be included in the team which designed and made a gift for Nancy Reagan.

After five years of employment Gad returned to Finland in order to start a business as a goldsmith in Helsinki. Gad Leinson is a pioneer in working with titanium. He came to understand titanium’s potential for beauty, design and durability very early on in his career.

​

Now in his fifties, Gad is a Nordic jeweler who is renowned for creating unique one-off pieces in Finland.

“I’ve always wanted to be free to focus on beauty, timeless design and quality. The experience gained over the years allows me to do this today.”
