Divergences where this body has a position on record
The divergences on this site compare four English wording columns (GIA, FTC, CIBJO and Gem-A). GB/T 16552 supplies the Chinese formal names, which is not one of those columns, so none of the 30 rows on the divergence index is filed under GB/T — its own recorded names appear on the entry pages instead.
