    Mined

    Mined diamonds have been supported and certified by the GIA since they started. Before the arrival of lab made diamonds, the only way to get a diamond was through the natural extraction of the gem from the earth. Other trusted lab’s such as AGL and IGI have grown in reputation and prominence throughout time.
