GIA to Offer Origin Determination for 3 More Gemstones
Starting Jan. 1, customers can request the service for opal, peridot, and demantoid garnet.

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.
“Our expanded services are based on GIA’s extensive research and collection of 32,000 samples collected by GIA field gemologists,” said Shane McClure, GIA’s global director of colored stone services.
“The institute started colored stone reporting more than 75 years ago, and, since then, researchers and gemologists 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 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 (current ones listed here) 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.
