AGTA Now Requiring Members to Call Lab-Grown Gems ‘Synthetic’
The association added the requirement to its revised "Code of Ethics" and released the 17th edition of its “Gemstone Information Manual.”
AGTA has released a new edition of its “Gemstone Information Manual” and revised its “Code of Ethics.”
Dallas—The American Gem Trade Association (AGTA) has updated its “Code of Ethics” and released the 17th edition of its “Gemstone Information Manual.”
The “Code of Ethics” is an outline of business practices that all AGTA members are required to commit to via signature annually.
Under the policy approved by the board of directors in June 2026, AGTA members must now use the word “synthetic” when describing a manufactured material that has “essentially the same chemical composition, crystal structure, and physical and optical properties as its natural counterpart.”
The term “lab-grown” may not be used alone to describe any man-made gemstone.
Retail jewelers may describe these materials as either “synthetic” or “man-made,” together with the name of the gemstone.
“Clear and consistent language is essential to consumer confidence,” said AGTA President Bruce Bridges.
“This policy gives AGTA members a straightforward standard for describing synthetic gemstones while reinforcing the association’s commitment to natural-colored gemstones.”
Since 2024, the association has banned lab-grown diamonds and gemstones from being sold on the show floor at its trade shows.

AGTA also released the 17th edition of its “Gemstone Information Manual,” which includes the addition of three symbols to the “Specific Forms of Enhancement” section.
They are “ASBL” for assembled stones, including doublets and triplets; “HR” for heating with residue; and “W” for waxing.
AGTA also updated entries in the “Gemstone Information Chart.”
The chart now identifies irradiation and heat as common, stable treatments for pink morganite.
The chart’s “Special Advice” column features updated care guidance. It cautions against ultrasonic cleaning for certain gemstones, including jade and moonstone.
Bridges recognized those who contributed to the new edition.
“The Industry Rules Committee’s diligent work keeps the ‘Gemstone Information Manual’ current and useful,” Bridges said.
“These updates help AGTA members apply consistent disclosure and care standards throughout the supply chain while continuing AGTA’s longstanding role in setting standards the broader industry follows.”
John W. Ford Sr., CEO of AGTA, also commented, “This trusted resource gives our members and the broader international gemstone industry practical, current guidance that supports responsible disclosure and ethical business practices.”
