New Collection of Gemstone Semi Precious and Precious Beads
Some of the stones are manufactured to imitate other precious stones. For example, cubic zirconia is a synthetic diamond simulant composed of zirconium oxide. Imitations with a real stone in color, but do not have a real chemical or their physical characteristics.
However, lab created gemstones are not imitations. For example, 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 fraction of the cost of natural stone. Smaller synthetic diamonds were produced in large quantities of industrial abrasives. Synthetic gem diamonds larger, high quality, especially in varieties of color, are also produced.
This gemstone is natural stone or laboratory-created (synthetic) stone, characteristics are the same for each. Laboratory-created stones are more vibrant colors to them, that pollutants are not present in the laboratory, so do not affect the clarity or color stone. However, natural gemstones are still considered more valuable, on average, because of their relative rarity.
The origin 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, while others are considered semi-precious.
