AMBER, a yellow translucent fossil tree resin which through loss of volatile constituents, oxidation and polymerization has attained a stable state. Burial time needed to reach this state may be millions of years and as “fossil” implies prehistoric life, the resin must have been exuded from a tree at least before recorded history. It occurs as irregular modules or droplike shapes in all shades of yellow with aspects of orange, brown and, rarely, red (Ezek 1:4, RSV gives “bronze,” NEB gives “brass”). Deeply colored translucent to transparent varieties are prized as gem material and have been used, since prehistoric times, for ornaments.
