Graduated Amber Barrel Necklace in Celluloid

• Amber - More frequently used to refer to the colour, than the material from which the word is derived, amber is the fossilized resin from ancient forests. It is not produced from tree sap, but rather from plant resin. The resin is aromatic, and can drip from and ooze down trees. In colour, it may be a deep honey colour, (amber), brown, or white. As it oozes out it fills internal fissures in the tree, trapping debris such as seeds, leaves, feathers and insects. The debris trapped within the amber can assist in dating the deposit.
  
  In its natural state it is found in rocks, on the sea floor (from where it may be washed up to the shore) and mined, using both open cut and underground techniques. About 90% of the world's amber comes from Russia. Amber has recently been discovered at Cape York in Northern Australia
  
  Amber is often incorporated in jewellery, and used in pipe stems. The shine on the surface of amber becomes even more intense when it is worn and used regularly. Genuine amber, when rubbed, will release a slightly musky scent.
• Celluloid - In 1864 an American scientist by the name of Parkes mixed camphor with nitrocellulose, etc. The result was what came to be known as "celluloid", the first form of plastic, and a product for which Parkes could find no use.
  
  Some time later when the supplies of ivory for making billiard balls were becoming difficult to obtain, an inventor produced a perfect billiard ball from a mould using "celluloid".
  
  Toys, dolls and other products such as combs, cutlery handles and costume jewellery made from celluloid began appearing on the market from 1913 and continued to do so until the early 1950s by which time it was superseded by more modern products due to safety concerns because it was highly flammable and brittle product.
