Hint: Amber is a fossilized tree resin that has been prized for its color and natural beauty since the Neolithic period. Amber has long been prized as a gemstone, and it is now used to create a variety of decorative objects.
Complete answer: Amber is made of resin. The sap transports nutrients around the tree, whereas the resin is semi-solid and serves as a defense response for the plant's immune system. The majority of amber discovered dates back 30-90 million years. Amber comes in a variety of colors and can appear in a variety of ways.
Amber is classified into five classes based on its chemical constituents. Because amber is formed from a soft, sticky tree resin, it may contain animal and plant material as inclusions. Amber found in coal seams is also known as resinite, and the term ambrite refers to amber found specifically in New Zealand coal seams.
Amber is typically a light honey color, but it can range from a white-ish color to almost black, and even blue or red. Amber is created from plant resin rather than tree sap. Glass, modern plastics, and synthetic and natural resins are used to create artificial amber.
Note: Amber is a unique preservational mode, preserving otherwise unfossilized parts of organisms; as such, it is useful in the reconstruction of ecosystems as well as organisms; however, the chemical composition of the resin is of limited utility in reconstructing the resin producer's phylogenetic affinity.
