Hi all 
I was wondering if anyone could tell me how Tanzanite is graded? Is it (as i think) graded by individual jewellers or channels, or is it by an "Independant body"??
My reason for asking, is that i recently heard a presenter say that the specific "AAA" Tanzanite he was selling had been graded by the Birmingham Assay office:cheeky: Which made me think. TYIA.
