Carlsbad, Calif.—The Gemological Institute of America will launch origin-determination services for three additional gemstones and debut redesigned colored gemstone reports next year.
Starting Jan. 1, 2026, GIA will offer origin-determination services for opal, peridot, and demantoid garnet.
It currently offers this service for alexandrite, emerald, Paraíba tourmaline, red spinel, ruby and sapphire, and recently began providing the service for untreated jadeite jade and omphacite jade from Myanmar (Burma) and Guatemala.
GIA also is launching redesigned colored stone reports next year.
The new reports will feature an “elevated design for enhanced storytelling,” the lab said, highlighting the most relevant gemological information so the trade and consumers can easily grasp the unique characteristics of the gem.
The lab is also revising the weight categories and related fees for colored stone submissions.
More details on this revision will be available on GIA’s website on Jan. 1.
Gemstones submitted to the lab on or after Jan. 1 will be subject to the new weight categories and fees and will also receive the redesigned reports.
