During his years as an architecture student, Dutch born Jan Gjaltema won a national contest for a new urban design of Rotterdam’s inner city, the "Weena prijsvraag ". At the end of the 1970s he received his Masters Degree in Architecture from the Delft Technical University in the Netherlands, where Rem Koolhaas currently teaches. After graduating, Jan began his career as a designer. During the 1970s he also studied lithography at the "vrije academie" "psychopolis" in The Hague.
Jan combines the linear and the structural with the modern and forward look to produce a most varied and distinctive collection of handcrafted sterling silver jewelry for both men and women. In 1983, he turned his full creative attention to fine jewelry design. All of his creations are handcrafted and fabricated - none are cast. He works with inlays of abalone, mother of pearl and resin in many different colors as well as with precious stones.
