About Amber:
- It is fossil tree resin that has achieved a stable state through loss of volatile constituents and chemical change after burial in the ground.
- Amber has been found throughout the world, but the largest and most significant deposits occur along the shores of the Baltic Sea in sands 40 to 60 million years old.
- Amber occurs as irregular nodules, rods, or drop like shapes in all shades of yellow with nuances of orange, brown, and, rarely, red.
- Milky-white opaque varieties are called bone amber.
- The turbidity of some amber is caused by inclusions of many minute air bubbles.
- Many hundreds of species of fossil insects and plants are found as inclusions.
- Deeply coloured translucent to transparent amber is prized as gem material.
- Ornamental carved objects, beads, rosaries, cigarette holders, and pipe mouthpieces are made from amber.
- Amberoid, or “pressed amber,” is produced by fusing together small pieces of amber under pressure. Parallel bands, or flow structure, in amberoid help to distinguish it from natural amber.
