Amber stone is not strictly speaking a stone at all, but is a fossilized resin from the now extinct coniferous tree, Pina Succinifera, which existed in the Eocene Epoch of the Tertiary period, about 50 million years ago, and comes mainly from the Baltic, although there are a number of other deposits throughout the world. Amber was the first precious stone noted in human history.  Amber has a Mohs rating of 2-2.5 on the hardness scale. Amber is thought to create a feeling of ease and being carefree; enhance memory of past lives; open receptivity on a mental/spiritual level.
