Unlike diamond, there is no universally accepted grading system for gemstones. Every company can "grade" their own stones and they will be 100% right. What company A consider as AA quality could be listed as AAA, or even AAAA, quality in company B's description. We have been in this business for over 30 years and we refuse to "label" our beads with the make up your own grade system because we know when you order from us, you will see the quality.
