About these stones
How we grade

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.
