I have been buying jewelry for my wife and our friends from Hans Koch and his wonderfully engaging and helpful staff for 20 years. Hans' education/training as a fabric designer shows in his impeccable sense of color and style -- applied to his jewelry designs equally as uniquely and ?adventurously" as to his exquisite handbags and belts. An extraordinary talent for rare combination and "working" of numerous, often "natural," materials (a few among them, antique African amber, Oriental jade, multi-hued semi-precious stones and, of course, leather) is, likewise, a hallmark of his jewelry "production." Constantly worn by my wife, Hans? jewelry has been greeted by absolute awe, seemingly bordering on jealously, in women all over the world! Astonishingly reasonable prices as well.
