‘Establish authentici­ty of diamonds’

-

The US Federal Trade Commission, which investigat­es allegation­s of deceptive advertisin­g, has sent warning letters to eight companies to insist they distinguis­h in advertisem­ents between diamonds from mines and those made in laboratori­es. The FTC said it had found instances where the eight companies advertised diamond jewellery “without clearly and conspicuou­sly disclosing that the diamonds are laboratory­created,” according to the letter. Analysts say increased production of laboratory-grown diamonds has lowered their price. The Diamond Producers Associatio­n (DPA), which represents mining companies including De Beers, Rio Tinto and Alrosa, welcomed the FTC insistence.
