Hi, I was wondering what GIA mean when they say additional twinning wisps not shown on their plotting diagrams. Why WOULDN''T they plot all the inclusions they can see? Is it a bad sign of the diamond having more inclusions than I think or is it that the additional ones are so minute that it isn''t worth plotting? or the reverse, that there are so many of them that if they plotted it, it would make the diamond look bad in the cert? I''m confused! Assuming it''s a VS2 diamond.
