Early 20th Century Baltic Amber Tribal Necklace, ca. 1920. Various hues of large amber beads strung on textile rope of red and tan. Acquired in Europe in 1960s. Ex: S. Zaremba collection, Florida. Total length of necklace is 31". Length of large amber bead is 16". The Baltic region is home to the largest known deposit of amber, called Baltic amber or succinite. It dates from 44 million years ago (during the Eocene epoch). It has been estimated that these forests created more than 100,000 tons of amber. The term "Baltic amber" is generic, so amber from the Bitterfeld brown coal mines in Saxony (Eastern Germany) goes under the same name. Bitterfeld amber was previously believed to be only 20–22 million years old (Miocene), but a comparison of the animal inclusions revealed that it is most probably genuine Baltic amber that has only been redeposited in a Miocene deposit. Other sources of Baltic amber have been listed as coming from Poland and Russia.
