About

Our History

Hans Kober, the owner of JFF Jeweler Supply, began his career as a hand engraver in Germany.  He moved to America in 1967 to work as the hand engraver at Cohen Co. Jeweler's Services in downtown Atlanta for Otto Cohen. In 1976, Hans and Otto decided to become business partners and open Just for Fun - Cohen Co in Doraville, GA. 

Just For Fun began as a jewelry repair shop with a small shelf carrying various jeweler's tools such as casting equipment.  Over time, the demand for jewelers tools was enough that Hans created a separate tools department in the early 1980s.  Hans' commitment to carrying only the best quality tools, built Just for Fun a solid reputation and following among jewelers in the South East.  With the success of the store, Hans decided to give up hand engraving completely in the late 1990s. 

In 2000, Otto Cohen retired, closing the repairs department.  Hans deciding to keep the jeweler supply store open, changed the name from Just for Fun, to JFF Jeweler Supply.
