FEDERAL TRADE COMMISSION USA

In 2018 the Federal Trade Commission in the USA published a statement about Laboratory Grown Diamonds. The FTC’s previous definition of a diamond stated: “A diamond is a natural mineral consisting essentially of pure carbon crystallized in the isometric system.” This is no longer applicable, the commission said Tuesday. The new listing does not include the word “natural.”

“When the commission first used this definition in 1956, there was only one type of diamond product on the market — natural stones mined from the earth,” the FTC said. “Since then, technological advances have made it possible to create diamonds in a laboratory. These stones have essentially the same optical, physical and chemical properties as mined diamonds. Thus, they are diamonds.” In the same ruling the FTC decreed that Laboratory Grown Diamonds should not be termed as synthetic as this would imply that they are a diamond imitation or fake, whereas in every technical parameter they are 100% diamond.

Comment by the International Grown Diamond Association on the FTC Ruling: “All reputed gem grading laboratories such as GIA, IGI, HRD Antwerp and GCAL among others acknowledge that laboratory grown and mined diamonds have identical properties. Both are 100% carbon and thus diamonds

Once the lab grown diamond has been graded, the diamond’s girdle is laser inscribed with an unique report number and the accompanying lab report bears a statement that the it is a 'laboratory grown diamond.' The grading labs use similar parameters to grade both, laboratory grown and mined diamonds.”
