MiaDonna Man-Made Diamonds also known as Cultured Diamonds or Synthetic Diamonds are REAL diamonds that are optically, physically and chemically identical to an earth-mined diamond. These diamonds are grown in modern-day lab environment that simulates the earth’s natural growing process of a diamond. Much like making ice in your modern-day simulated environment called your freezer. Unlike earth-mined diamonds, these diamonds are free from any negative environment and humanitarian concerns that are associated with getting them out of the earth.
