Purity Grade – Purity grade is the second phase of the larimar grading chart. When we considered purity we are referring to any substance or stain that is foreign to the stone. For sample the Larimar could be a AA blue and have a spot or spots in some part of the stone, this could be a grey, brown or any other color that takes away from the larimar piece. Purity grade is mostly use when grading cabochons or beads. When buying slices of Larimar you must take into consideration of the size of the slice in comparison to the size of the foreign substance.
