Closer Look

Certain trees, especially conifers, produce a sticky substance called resin to protect themselves against insects. Normally, it decays in oxygen through the action of bacteria. However, if the resin happens to fall into wet mud or sand containing little oxygen, it can harden and eventually fossilize, becoming the yellowish, translucent substance known as amber. If any insects or other organisms are trapped in the resin before it hardens, they can be preserved, often in exquisite detail. By studying these preserved organisms, scientists are able learn key facts about life on Earth millions of years ago.

Etymology

Origin of amber

1350–1400; Middle English ambre < Old French < Medieval Latin ambra < Arabic ʿanbar ambergris; confusion of the dissimilar substances perhaps because both were rare, valuable, and found on seacoasts

Explanation

Amber is a brownish yellow color. Many cats have green eyes but those with amber eyes are likely to have yellow or white fur. Amber is also a translucent golden or honeyed-yellow colored gemstone, often used to make jewelry. That's where the color amber gets its name. Amber comes from the ocean floor — most of it is harvested from the Baltic Sea off the coast of Russia. The most likely origin of amber is the Latin word for "bitter," amarus, as the color yellow was often associated with bitterness and envy.
