There are three primary types of gemstone products:

  • Natural gemstones occur in nature and can be rare and expensive.
  • Laboratory-created stones — which also are referred to as synthetic, laboratory-grown, or manufacturer-created — have the same chemical, physical, and visual properties as natural gemstones, but they aren’t as rare and often are less expensive than natural gemstones with similar characteristics.
  • Imitation stones look like natural stones, but may be made of glass, plastic, or other less costly material.

Laboratory-created and imitation stones should be clearly identified as such.
