GIA has observed a significant increase in coloured gemstones submitted for testing as it steadily expands its network of laboratories worldwide, according to Shane McClure, global director of GIA Colored Stone Services. Enhanced offerings Origin determination and treatment detection are the primary reasons for most testing submissions, prompting GIA to expand its offerings in these areas. Opal, peridot and demantoid garnet were added to GIA’s origin-determination service on January 1, 2026. This follows the 2025 launch of a service for untreated jadeite jade and omphacite jade to determine whether the jade originated from Myanmar or Guatemala. GIA country-of-origin service is also available for alexandrite, emerald, Paraiba tourmaline, red spinel, ruby and sapphire. “Our expanded services are based on GIA’s extensive research and collection of 32,000 samples collected by GIA field gemmologists,” said McClure. “The institute started coloured stone reporting more than 75 years ago and since then, researchers and gemmologists across our laboratories have developed an industry-leading knowledge. This expertise, as well as GIA’s decades-long commitment to research, underpin our report results.” GIA’s full suite of gemmological reports for coloured gemstones have also undergone a substantial upgrade. The redesigned reports feature an elevated layout that highlights more gemmological information for enhanced storytelling. Weight categories and fee structures for coloured stone submissions have likewise been revised. Delivering breakthroughs in gemstone provenance GIA: GIA开创宝石溯源新纪元 The Gemological Institute of America (GIA) is stepping up its origin determination and treatment detection services for coloured gemstones amid heightened market interest in provenance and responsible sourcing. 随着市场对宝石溯源与负责任采购的关注度日益增长，GIA美国宝石研究院正 全面提升彩色宝石的原产地鉴定与加工处理检测服务。
