Graduating from the Werkkunstschule Schwäbisch Gmünd, Germany, with a focus on Industrial Design, he honed his craft and co-founded frogdesign from 1971 to 1982. Since 1982, Spreng has charted his own path as an independent designer and jewellery creator, splitting his time between Canada and Germany. His expertise in industrial design infuses each piece of jewellery he creates with geometric precision, marrying form and function in exquisite harmony. Spreng's jewellery is a testament to his meticulous craftsmanship and artistic vision. Crafted from precious materials such as gold, platinum, and gemstones, each piece boasts clean lines and distinctive names like ice cream cone rings, Caro, Twiggy, and Blub. From rings and brooches to necklaces and pendants, each creation is a unique masterpiece, meticulously crafted according to Spreng's own designs by a select team of artisans. One of Spreng's defining characteristics is his unwavering commitment to sourcing the finest materials for his creations. He scours the globe for rare gemstones, leveraging his extensive network of contacts to procure the most exceptional materials. Many of the stones he uses are one-of-a-kind pieces whose rarity and value only appreciate with time. What sets Spreng apart is his aspiration to create pieces of timeless beauty and durability. He endeavours to imbue each piece with a sense of immortality, envisioning them as artifacts that transcend generations. I want this jewellery to be unearthed somewhere in a few thousand years and still retain its essence, serving as a reflection of our current era, he says. Already, some of Spreng's creations have achieved iconic status, earning a permanent place in renowned museums such as the Museum of Modern Art in New York. With each piece, Spreng leaves an indelible mark on the world of high jewellery, crafting treasures that stand the test of time.
