carat is no1, cut is no2, color and clarity are no3 and no4, out of 4c.
most valueable is size and fire visible. cut determines fire (best is, tripple x, table %53-57, depth%60-62.8). color and clarity normally are not visible to naked eyes of non-professionals as long as >= color I and clarity vs2
tiffany does not use GIA, which is used by all others. diamond is just standard product, tiffany is the same quality as all others.
