1. Natural Gemstones

Natural gemstones come from the purest source--mother nature. They are created naturally over a long period of time without the aid of humans. They are found within the earth, along riverbeds, lining rocky cliffs and at other locations. Since they were naturally formed, unique "inclusions" within the gemstone may be observed. Some may be later treated to enhance clarity and color

 

2. Synthetic Gemstones

Synthetic gemstones have all the visual, chemical and physical properties of their natural counterparts, but they are created in a laboratory via a quick process. Synthetic gemstones usually appear flawless without unique "inclusions". Since they can usually be produced in large quantities in the lab, their value is significantly lower than Natural gems.

 

3. Imitation Gemstones

Not having the same chemical properties of natural gems, imitations are made of glass, plastic, ceramic or other materials, but they are created to resemble natural stones. One of the most well-known imitations is cubic zirconia, which has been widely used and commercialized alongside diamonds for over three decades.
