GIA Certified Mined Diamonds
Natural diamonds mined from the Earth carry a sense of heritage and timelessness. At TR GEMS, we are committed to providing wholesalers, jewelers, and jewelry manufacturers with premium, certified natural loose diamonds that comply with the Kimberley Process.
Every diamond is sent to the Gemological Institute of America (GIA) or International Gemological Institute (IGI) for grading. Our master cutters polish these raw stones to Triple Excellent (3EX) standards, maximizing fire, scintillation, and brilliance.
