Synthetic gemstones are man-made stones that mimic the appearance and properties of natural gemstones. They are created in laboratories using various techniques, such as the Czochralski process or hydrothermal synthesis, which replicate the conditions under which natural gems form. These stones can be produced in a variety of colors and qualities, often at a lower cost than their natural counterparts. While synthetic gemstones share the same chemical composition and physical properties as natural ones, they are distinct in origin. They are often more environmentally friendly and ethically sourced, as their production does not involve mining. Popular synthetic gemstones include moissanite, cubic zirconia, and synthetic emeralds.
