GLS Jewelry reports provide all gemstone and mounting specifics, as well as clear standardized photos showing details of craftsmanship that may not otherwise be visible.

A total commitment to understanding consumer concerns has motivated GLS to develop rules and procedures for information provision on any item which can be analyzed, according to the laws of our fields of specialty. This empowers jewelry buyers to find precisely what they want, with complete confidence in the accuracy and authority of the GLS documentation.

Gemstones should only change hands when accompanied by a grading report attesting to quality. Regardless of location or marketplace, an authentic GLS Laboratory Report is the common language of trust and confidence in the gemological world.
