Hello. I’m Robert Gessner, founder and CEO of Gessner Gems. I have spent my career, which is now 17 years, in the colored gemstone world starting where one should, and that is on the mines. As a trained and Professional Geologist, I spent a total of 13 years on some of the world’s most famous large scale and professionally run mines, namely TanzaniteOne (for tanzanite) and Gemfields’ Kagem Mine (for emeralds) being responsible for the exploration and mining, production and planning of the projects.

In 2015, ventured from Africa to the United States, and completed my Graduate Gemologist at the GIA. Following the completion of the gemology course, I started Gessner Gems. Gessner Gems is empowering a new generation of online consumers that no longer need to be confused or unsure about colored gemstones; we are providing a much needed fresh look to colored gemstone jewelry and consumer confidence to buying colored gemstone jewelry online.
