An imitation gem may be made of flint glass, often silvered on the back to increase the brilliance. Since World War II, colored plastics have replaced glass, especially in costume jewelry. Plastics are cheaper, more easily molded, and lighter in weight.During the 19th century, artificial pearls were made by blowing hollow beads of glass and pouring into them a mixture of liquid ammonia and the white matter from the scales of fish such as the bleak, roach, or dace. A much better type of artificial pearl, the indestructible bead, was introduced shortly after 1900. The bead is made of solid glass with only a narrow hole for the thread. Pearl essence, consisting of the crushed scales of certain herring, is applied to the outside of the glass and covered with a transparent, colorless lacquer.The most successful imitation of a diamond is strontium titanate, made by a flame-fusion technique. Its index of refraction is almost identical to that of a diamond, and it has a higher dispersion. Thus ...more

Synthetic gemstone is identical to a natural gemstone in almost every way. This includes the same basic crystal structure, refractive index, specific gravity, chemical composition, colors, and other characteristics. Since the same gemological tests are used for stone identification on both natural and synthetic gems, it is sometimes even possible for a gemologist to be puzzled as to whether or not a stone is natural or synthetic. When this occurs, the best course of action is to send the stone to an accredited gem laboratory, like the Gemological Institute of America. They can positively determine whether a stone is synthetic or naturally occuring. Only minor internal characteristics allow separation of a synthetic gemstone from a natural gemstone. Jerkin or American Diamond is the best substitute of a real diamond.
