A lab-created 1.64 carat, cushion brilliant cut diamond, color grade I (near colorless), clarity grade VS2 (very slightly included).

Only 2% of mined diamonds fall into the category Type IIa. As grown means the diamond is not subjected to clarity treatment through laser drilling or fracture filling.
