Before purchasing a diamond, we require you to review a copy of its certificate or report as proof that
the diamond has undergone an independent impartial grading service
by a qualified diamond grading laboratory.
At Jewelstar Ltd we recommend one of the following two diamond laboratories.
GIA Diamond Report
A GIA Diamond Report documents the specific characteristics of a diamond, issued by
the Gemmological Institute of America (GIA), one of the most respected experts
in the diamond industry. The GIA set the standard for diamond grading.
IGI Diamond Report
An IGI Diamond Report documents the specific characteristics of a diamond, issued
by the International Gemmological Institute (IGI), according to the strict
international standards for which IGI is known.
