R.I. information can be retain online and most of the major labs like GIA or GRS doesn’t state this fact as they already tested it, before determining the particular gemstone family & species. Also, ‘R.I.’ information in particular is not very useful as even ‘synthetic emeralds’ will have similar R.I. value. What is more important is to determine if particular gemstone is natural or synthetic (man-made). Thanks for the question!
Why R.I. is not given? Though mentioned “NATURAL EMERALD”.
