Amber

Amber
Amber is one of the organic gemstones, being the time-hardened fossilized resin of pine trees, the now extinct pinus succinifera, and others. As such it varies from about 20 to 60 million years old, according to different sources. It appears surprisingly light and warm to the touch, and readily produces static electricity when rubbed. Indeed it was known to the ancient Greeks as elektron, and it is from this that we have obtained the word electron for the negatively charged particle, and also the word electricity. The metal electrum was so called because of its similarity in colour to amber. Amber is known in German as bernstein because in the middle ages, powdered amber was burnt as an aromatic incense.
Colour
Amber is most usually similar colours to honey, varying from golden yellow, through rich orange and red to brown, but some can be white, dark brown almost to black, blue or green.
