However, Gemstones created in lab are not imitations. For example, diamonds, ruby, sapphires and emeralds have been manufactured in labs to possess identical chemical and physical characteristics as with the naturally occurring variety. Synthetic corundums, including ruby and sapphire, are very common and they cost only comparatively lesser than the natural stones. Smaller synthetic diamonds are manufactured in large quantities as industrial abrasives. In addition larger synthetic diamonds of gemstone quality, especially of the colored variety, are also manufactured.
Some gemstones are manufactured in order to imitate other gemstones. As an example, cubic zirconia is a synthetic diamond simulant composed of zirconium oxide. Moissanite is another similar example. The imitations copy the look and color of the real ones but possess neither their chemical nor physical characteristics.
Whether a gemstone is a natural stone or a lab-created stone, the characteristics of each are similar. Lab-created stones usually tend to have a more vivid color to them, as impurities are not present in a lab, so therefore do not affect the clarity or color of the stone.
