Since its founding in 1934, the American Gem Society has protected jewelry buyers from fraud and false advertising. They have achieved this premier standard by educating jewelers and vetting any jeweler who applies for AGS membership. Today the American Gem Society remains an exclusive organization with only 1 in 20 jewelers meeting the requirements. R.F. Moeller is honored to be a member of this esteemed society.
