Book excerpt: Jewellery styles were influenced by wars, the economy, events like the Centennial Exposition in Philadelphia, and the growth of industrialisation. Sentiment was reflected in hair jewellery made from a loved one's hair, lockets containing family pictures, and pins bearing names and catch-phrases of importance to their period. This book gives you the historical background, the periods' fashion trends, and detailed descriptions of popular jewels, so you can have an even greater appreciation for the pieces in your collection. The book also includes information about: How jewellery is manufactured; How to determine what kind of metal an item is made from; Determining whether a stone is synthetic; A listing of maker's marks to help you identify and date pieces.
