Amber and Tortoise Shell Earrings with Gold Fittings

• 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.
• Tortoiseshell - Tortoiseshell is a translucent material that comes from the horny carapace of a certain types of turtles, including the hawksbill turtle. It is often therefore mounted on a colour underground - often red - or inlaid with gold or silver thread, as seen in Boulle furniture.
  
  The texture and colour nuances of the material are extremely important. Heated tortoiseshell can easily be formed into various shapes. Like other natural materials, tortoiseshell becomes more beautiful with use. In a time before plastic, tortoiseshell was widely used for small objects such as combs and powder compacts.
  
  In 1973, the trade of tortoiseshell worldwide was banned under CITES (The Convention on International Trade in Endangered Species). Prior to importing or exporting items containing tortoiseshell a CITES permit must be obtained. Tortoiseshell items cannot be traded on Ebay.
  
  "Faux tortoiseshell", another case of man initiating nature, is made from old-style plastics such as celluloid and cellulos and is coloured with red, yellow and brown spots to imitate the genuine article. It is commonly used in glasses frames, musical instruments and costume jewellery.
