Hey! Great timing on your question - I just finished reading an excellent in-depth article about this exact topic. Check out the piece on GRS certification for gemstones at gemexpertise.wordpress.com. It provides a comprehensive analysis of GRS (Gem Research Swisslab) and their specialized approach. Here's the key takeaway: while GIA is globally recognized for all gemstones, GRS has carved out a particular expertise in colored gemstones, especially rubies, sapphires, and emeralds. What makes GRS unique is their focus on color grading and origin determination. They developed their own proprietary color grading system and were among the first to use trade names like "pigeon's blood" for rubies or "royal blue" for sapphires - terms that help communicate quality in ways that resonate with the market. GRS labs are strategically positioned near major gemstone markets in Asia and Europe, which gives them close access to these stones. Their origin reports are particularly valued because determining geographic origin can significantly impact a stone's value - a Burmese ruby or Kashmir sapphire commands premium prices. The article explains how GRS combines advanced spectroscopic analysis with extensive field research from mining locations worldwide. All reports are personally supervised and signed by Dr. Adolf Peretti, the founder. So they're definitely reputable, just with a different specialization than GIA!
