      About these stones

      How we grade

      A: lighter colour, visible inclusions. Good for fashion pieces and practice settings.

      AA: even colour, some inclusions you can see up close. Everyday jewelry.

      AAA: rich colour, eye clean. Fine jewelry.

      AAAA: the top colour we cut, eye clean. Statement and heirloom pieces.

      Market Basics or Precision

      Market Basics: good outlines; sizes and depths vary a little stone to stone. Best value for settings you adjust by hand.

      Precision: even outlines and matched depths. Drops into pre-notched castings and lines up in rows and halos.
