Gemological Products originated in Santa Monica in the 1980's. Across the street from GIA we operated our showroom to promote or main products: The Portalab, Gem Lab, Gem Pro Microscopes, and Gem Pro Refractometers. In addition we offered other items that have traditionally appealed to the jeweler/gemologist appraiser. Over the years our high quality and superior service have made us a favorite of the gemological community.

At our current facility in Sunriver Oregon we continue to offer a line of unique and largely US made products. Our Portalab has a 30 year history of dependability and usefulness. If you must go somewhere and you need your microscope there is nothing easier to pack than your Portalab. Our Gem Pro microscopes have become the staple of labs and jewelry stores worldwide. Our innovative darkfield and bulletproof electronics have made this a favorite.. The Gem Pro refractometer has enjoyed success with its design over the years. Its superior hemicylinder glass makes it in a class of its own. Everything that should be in a gemology refractometer is there. We try to offer products that are both useful and offer years of dependability. Check out or products page or email us with questions.
