Colored stones fall into four basic categories: precious stones, semi-precious stones, synthetic or lab created stones and imitation stones.
Many years ago an arbitrary separation was made in the then known world of gemstones. Two major categories were created: precious and semi-precious.
Precious stones were those in high demand, which commanded consistently higher price for fine quality samples. In this category were: diamond, ruby, sapphire, and emerald.
Semi-precious stones were those whose popularity was ruled mainly by fashion. This category was more of a catch all for the remaining stone types, such as: amethyst, garnet, periot, topaz, aquamarine, tourmaline, etc.
Lab Created Gemstones are man made. To qualify in this category, a stone must have the same chemical composition, crystal structure, optical properties, hardness and appearance as its counterpart in nature. According to the FTC, only stones having these properties may be classified as lab created.
Synthetic or Imitation stones, while also created by man, share only in appearance with a natural counterpart. The composition of the stone is irrelevant. It may be made of glass, plastic, paste, or some other crystal structure, which resembles to some extent a natural gemstone.
