Amber

Amber is not a stone, but a fossilized resin of coniferous trees (such as pine), the Oligocene period, so sometimes we find inside it complete specimens of insects or plants.

Amber is perhaps the oldest substance used by humans for the manufacture of jewelry. They have found jewels of these that date from the year 8000 A.E.C. (Before common Era).

Given its warm touch and the fact that it sometimes contains insects, it was believed that it possessed life. In ancient China, they considered that amber was the spirit of the tigers that transmuted into that resin when they died. He was worshiped by the followers of the Mother Goddess in classical times, for it contained the very essence of life.

In Classical Greece it was called "elektron", since rubbing it against wool produces static electricity, and from it derives the word electricity.
