The Gemological Institute of America (GIA) has announced it will introduce redesigned coloured stone reports and expanded origin-determination services on 1 January 2026.
The new reports will feature a refreshed visual design that emphasises key gemmological information, helping both professionals and consumers better understand the unique qualities and provenance of each gemstone. The updates mark a significant evolution in how GIA communicates gem data, aligning aesthetics with scientific precision.
Among the major updates is the introduction of origin-determination services for opal, peridot and demantoid garnet. These additions extend GIA’s existing country-of-origin services, which already cover gemstones such as alexandrite, emerald, Paraíba tourmaline, red spinel, ruby, sapphire, untreated jadeite jade, and omphacite jade from Myanmar and Guatemala.
“Our expanded services build upon decades of research and the analysis of over 32,000 samples collected by our field gemmologists,” said Shane McClure, GIA’s global director of coloured stone services. “This work reinforces our commitment to scientific excellence and transparency in gem testing.”
GIA will also revise its weight categories and related fees for coloured stone submissions. The updated fee structure and redesigned reports will apply to stones submitted on or after 1 January 2026. (Photo courtesy: GIA)
