IMITATION AND SYNTHETIC STONES

There will always be a market for imitations or cheaper gems because of the value of gemstones and their rarity,. Generally imitation gemstones are made to deceive. They are made from any material, natural or artificial, that looks similar enough to be taken for the real and more expensive gem. Imitations have been made since thousands of years, for example blue faience (glazed day) was used by the Egyptians to imitate turquoise. Romans and Indians used coloured glass to imitate gemstones includ­ing emeraeds and rubies. The Victorians used a number of materials including glass (paste), plastics and resins to imitate both the natural mineral gemstones and the organic gems such as amber and shell.
