这本《ZEITGEIST(精)》的主要内容是：The author was able to study many early documents and photographs in Idar-Oberstein archives as well as pieces of jewellery that, taken together, are highly instructive on the history of costume jewellery. A vivid image of twelve jewellery manufacturers is evoked; proprietors and employees, production conditions, models policy, pieces of jewellery in each period style and worldwide marketing and distribution. Costume jewellery from Idar-Oberstein was not usually marked (stamped) because it was sold through wholesalers; this is what makes attribution to specific makers quite difficult today.
