What defines a synthetic gem?

A synthetic gem is specifically defined as a laboratory-created gem that possesses the same chemical composition, physical properties, and optical characteristics as a natural gem. This means that although synthetic gems are produced in a controlled environment, the end result is identical to that of a gemstone formed through geological processes.

Unlike natural gems that take thousands of years to form, synthetic gems can be created in a matter of days or weeks. This method of production allows for greater control over quality and consistency, often resulting in gems that are more flawless than their natural counterparts. Importantly, synthetic gems are not mere imitations; they are real gemstones with genuine properties found in nature, making their classification distinct from other types of gems.

In contrast, options that refer to natural gemstone formation, treatments, or visual imitations do not accurately represent the unique qualities that define synthetic gemstones.
