If people have been collecting objects of art (jewelry) for over 25,000 years why haven’t we found more jewelry than we have?   To answer that question lets look briefly at the Egyptian dynasties that encompass some 3000 years.  Clearly the Egyptians highly valued gold and gemstones.  They excelled at prospecting, mining and manufacturing jewelry. As rich as many of these dynasties were they were limited by the extent of known mineral resources.    Demand was high. Supply was limited.  Throughout the ages tombs of Pharaohs were pilfered for the treasures they held.    It is likely this plunder was melted down and reused. 

Today jewelry damaged or out of style is recycled.  Sometimes the pieces are reworked into more contempoary designs.  Sometimes the metal is sold as scrap.   Whatever the outcome the precious metals and gemstones are saved for later use.
