Natural vs Laboratory-Grown vs Imitation Gemstones: What Buyers Should Know

Three Terms That Mean Different Things

Natural gemstones form through geological processes. Laboratory-grown gemstones are created by people and, when they are true synthetic versions, share essential material properties with the corresponding natural gem. Imitations are materials designed to look like a gemstone but have different composition or properties.

Natural Gemstones

Natural gems are recovered from nature. Price can depend on variety, colour, clarity, cut, size, reliably established origin, treatment status, and demand. Natural does not automatically mean untreated or higher quality.

Laboratory-Grown Gemstones

Laboratory-grown rubies, sapphires, emeralds, and diamonds can share important properties with natural versions. Their origin should be disclosed clearly, and pricing and resale markets may differ.

Imitation Materials

Glass, plastic, and other gems may imitate a more expensive stone. An imitation may be attractive for jewellery, but it should not be misrepresented as the gemstone it resembles.

Questions to Ask Before Buying

  • Is the stone natural, laboratory-grown, or an imitation?
  • Has it been treated, and how?
  • Is there an independent laboratory report?
  • Does the report describe this exact stone?
  • What are the return and disclosure policies?

Frequently Asked Questions

Are laboratory-grown gemstones real?

They are genuine synthetic versions of the corresponding gem material, rather than natural stones. The distinction is their origin.

Can I tell the difference by looking?

Not reliably in every case. Professional gemological testing may be required.
