Baltic Amber Necklace
18 inches - 8 grams
Amber is a fossilized resin, not tree sap. Sap is the fluid that circulates through a plant's vascular system, while resin is the semi-solid amorphous organic substance secreted in pockets and canals through epithelial cells of the plant. Land plant resins are complex mixtures of mono-, sesqui-, di-, and triterpenoids, which have structures based on linked isoprene C5H8 units (Langenheim, 1969, p. 1157). Volatile terpenoid fractions in resins evaporate and dissipate under natural forest conditions, leaving nonvolatile terpenoid fractions to become fossilized if they are stable enough to withstand degradation and depositional conditions. The fossil resin becomes incorporated into sediments and soils, which over millions of years change into rock such as shale and sandstone.
Therefore, amber is formed as a result of the fossilization of resin that that takes millions of years and involves a progressive oxidation and polymerization of the original organic compounds, oxygenated hydrocarbons. Although a specific time interval has not been established for this process, the majority of amber is found within Cretaceous and Tertiary sedimentary rocks(approximately 30-90 million years old).
