The terms “synthetic” and “simulated” are often used interchangeably when discussing gemstones. The truth is, these two types of gems are different:
* Synthetic gemstones. Also known as artificial, man-made, lab-made, and lab-grown stones, synthetic gems are stones that were created in laboratories rather than nature. There are many processes that can be used to synthesize gems, and while they range in price, all are conducted artificially within a lab.
* Simulated gemstones. When gems are synthesized in a lab in order to imitate natural stones, they are called simulated gems. Not all simulated gems are synthetic. Glass pieces are often used to simulate natural gems, and one kind of natural gem could also be presented as another. For example, a natural garnet doublet could be cut in order to resemble a ruby.
