D.F. Weber was founded in 1869, Eisingen, Pforzheim, the cradle of gold and jewellery-making in the southern part of Germany. As an affiliated brand of LOTOS, D.F. Weber insists on producing eyewear from the unique precious metals - Palladium-Silver, worldwide exclusively used by D.F. Weber. Every piece of each D.F. Weber frame is made from a patented metal named "Palladium-Silver (PdAg 400 / 400)", which is a unique mixture of two precious metals—pure palladium and sterling silver. Owingto its Mohs hardness of 4.5–5.0, spectacles made of palladium are harder yet lighter than normal. This ensures the product's durability as it resists scratching, while its natural shine enhances the product's beauty. Imbued with the perfect combination of classic and modern aesthetics, D.F. Weber frames endure across time.
