This is a brightness chart put out by the opal association.The previous system was 5 ratings with 5 being the brightest.There are other computer models that use up to 55 brightness grades but it was decided to have only 7 grades.The brightest stone is B1 with the dullest being B7. So when you see a brightnes scale remember to check what system is beings used.
