I am looking for a stone recently and find that AGS'' certifications are different ? basically all of them have 4C info but different in many details . some cut grading have "light performance";"proportions factors";"polish";"sym" for detail and some just have "idea (0)". Do they have different standard and different idea(0) ?
also some are called "Diamond Quality Document",but some "Platinum light performance Diamond Quality Document" which has a "computer pic ",I am totally confused .
