Acquired from a storage sale close to home. Based on my quick research, this unit is used to analyze gem stones. Condition is used so please refer to the photos to hopefully get a general idea of state. Photos shows this unit in as found condition. What is shown is what’s being offered. This unit turns on ( green light) and no other testing performed. If you have questions please ask. Shipping is via Fed Ex only within the United States. I will have them pack and ship to your location. Thanks for stopping by!
