Colorado Gem Services LLC aims to provide reliable independent colored gem reports at an unbeatable price. Our unique business model frees CGS gemologists from time-consuming paperwork, enabling them to analyze more stones. That means bulk savings, which we pass on to our clients.
Every gem entrusted to us is examined in the USA by a highly trained and accredited professional gemologist using traditional gemological equipment and advanced scientific analysis such as FTIR, ED-XRF and Raman spectroscopy. We combine modern analytical techniques and extensive practical skills to interpret gemstone characteristics. No students. No shortcuts. No conflicts of interest – we’re not gem dealers.
