Some of the stones are artificial to imitate other precious stones. For instance, cubic zirconia is a synthetic diamond stimulant composed of zirconium oxide. Imitations with a real stone in color, but do not have a real chemical or their physical uniqueness.
But, labs created gemstones are not imitations. For instance, ruby, sapphire and emeralds have been produced in laboratories, to have identical physical and chemical properties of natural varieties. Synthetic (lab created) corundums, including sapphire and ruby, and very often they are only a portion of the cost of natural stone. Smaller synthetic diamonds were produced in large quantity of industrial abrasives. Synthetic gem diamonds larger, high qualities, especially in varieties of color, are also produced.
This gemstone is natural stone or laboratory-created (synthetic) stone, uniqueness are the same for each. Laboratory-created stones are more vibrant colors to them, which pollutants are not present in the laboratory, so do not affect the clarity or color stone. Though, natural gemstones are still considered more valuable, on average, because of their relative rarity.
The source of the gemstones also does not affect its classification as a semi-precious and precious stones. Rubies, emeralds and sapphires are always gems, precious stones, as others are considered semi-precious.
