| Types of Gemstones|
Organic Gemstones :: Organic gemstones have their origin either from plants or from animals. Like natural Pearls form around foreign bodies that have made their way inside the shells of marine or freshwater shellfish. Cultured pearls are produced artificially in large fisheries, many in the shallow waters off the seashores. Shells, which are regarded as gems, may come from animals as diverse as snails and turtles, living in the ocean, in fresh water or on land. Coral is made up of the skeletons of tiny marine animals called Coral Polyps. Bone or Ivory from the teeth or tusks of mammals, may come from recently living animals or from fossils thousands of years old. Amber is fossilized tree resin, collected from soft sediments or the sea. Jet is fossilized wood, found in some sedimentary rocks.
Because of the way the synthetic gems are made, they show subtle differences
in shape and colour that help to distinguish them from their natural counterparts.
Similarly, the synthetic gems have inclusions, which are different from
the natural inclusions. The experts can identify them and distinguish.
