About Us

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.

    We think colored stones rock

    Puns aside, most gemologists focus on diamonds and not too many have specialized knowledge of colored stones. Our team brings together a wealth of experience in this fascinating field.

  • 💥

    More bang for your buck

    We’re proud to provide basic certification with more detail than most for a lot less. If you need advanced scientific testing, you’ll find our prices hard to beat.

  • Your stone is safe with us

    We’ve all heard the horror stories about dubious Asian vendor/labs swapping out stones.  Just another reason to have your gemstones certified right here in the USA.
