History

Georgian c1714 - 1830
*prepared by hand
*use of artificial substances began in this period such as:
  rhinestones & pastes (usually had foil backs) instead of diamonds
  pinch beck (copper & zinc alloy) instead of gold
  cut steel & marcasite instead of silver
*diamonds or subs were commonly rose cuts or flat

Queen Victoria reigned from 1837 until her death in 1901.  Consequently, many pieces of jewelry can be referred to as Victorian.  Keep in mind there is never a clear-cut line dividing these periods.  Some styles and motifs continued to be popular for a longer period of time in some areas.  Styles also tend to overlap.  A style that was on its way out in England could be at its peak of popularity in the United States.

Arts and Crafts c1890-1914

Art Nouveau c1895-1917

     For an in-depth look at this influential time in history from an authority, check out The Story of Art Nouveau.  George Philip LeBourdais, takes the reader on a journey back in time.  You'll be swept into a world experiencing an anticipated freedom from the heavy and rigid industrial style that had gone on too long according to many.  A well deserved mention of Louis Comfort Tiffany's contributions was not overlooked.  Provocative artwork displayed prominently, a detailed timeline along with a line up of the movement's leaders completes a well-rounded editorial. I would expect nothing less from Artsy (Magazine). Check it out.
