Natural and laboratory-grown diamonds are both diamonds, but they have different origins. The distinction matters for product descriptions, sourcing records, customer expectations and any grading or identification documentation associated with a stone.

Natural diamonds

Natural diamonds form in the Earth through geological processes over very long periods. They are recovered from natural deposits and then cut and polished for use in jewelry. Their characteristics vary from stone to stone, which is why an individual diamond may be described using its own measurements and grading information.

Laboratory-grown diamonds

Laboratory-grown diamonds are created in controlled environments using technological processes that reproduce conditions for diamond crystal growth. They have the same essential crystal structure and chemical composition as natural diamonds, although their growth history and identifying characteristics differ.

Laboratory-grown does not mean imitation. It describes a diamond with a laboratory origin. The exact disclosure terminology should follow the applicable market rules and the documentation for the stone.

What laboratory-grown diamonds are not

Moissanite and cubic zirconia are not laboratory-grown diamonds. They are different materials that can be used as diamond simulants because of their appearance. A simulant may resemble diamond but does not have the same material identity. The GIA guide to simulants, moissanite and laboratory-grown diamonds explains these distinctions.

How should the difference be documented?

For a jewelry specification, record:

  • Whether the diamond is natural or laboratory-grown.
  • Its measurements and carat weight, where applicable.
  • The grading or identification report required by the buyer.
  • Any disclosed treatment or special characteristic.
  • The report number and issuing laboratory, where a report is supplied.

Do not rely on a photograph or a seller's broad phrase to establish origin. Identification requires appropriate gemological examination and documentation.

How should brands describe the options?

Use a clear material name near the product description. Do not use “created diamond” in a way that obscures origin, and do not describe moissanite or cubic zirconia as laboratory-grown diamonds. If a piece uses a simulant, name the simulant.

The FTC Jewelry Guides provide guidance on truthful representations of gemstones and laboratory-created or imitation substitutes in the United States. Requirements in other markets should be checked separately.

Choosing between natural and laboratory-grown

The choice may involve personal preference, budget, sourcing priorities, availability, design requirements and the importance a buyer places on origin. There is no single choice that is right for every customer. Compare stones using accurate material descriptions and relevant documentation rather than relying on general statements about appearance.

Frequently asked questions

Are laboratory-grown diamonds real diamonds? They are diamonds with a laboratory origin. Their origin differs from natural diamonds, and the distinction should be disclosed.

Can a jeweler identify a laboratory-grown diamond from a photograph? A photograph is not a reliable method for confirming origin. Appropriate gemological testing and documentation are needed.

Is moissanite a type of laboratory-grown diamond? No. Moissanite is a separate gemstone material and is commonly used as a diamond simulant.

Specify diamond origin clearly

For custom jewelry, confirm whether the design calls for natural diamond, laboratory-grown diamond or a different stone. Discuss gemstone options with VELORA MUSE and make the required disclosure part of the specification.
