Laboratory-grown diamonds
Laboratory-grown diamonds are diamonds produced using technological processes rather than formed naturally underground. Their origin should be stated clearly.
Compare with care
Laboratory-grown diamonds are not the same category as diamond simulants such as cubic zirconia. Natural and laboratory-grown diamonds can share gemological properties while differing in formation history and market value.
Read the available assessment
Check the laboratory’s identification and assessment for the individual stone. Do not assume identical reporting terminology across laboratories or report dates.
