The science of gemology is fascinating not only for the professional but for the gemology hobbyist. Both the professional and the novice have one thing in common, the need for a high quality microscope. A good microscope is essential in seeing inclusions. These are flaws in the stone that allow the gemologist to know whether or not the stone is nature made or man made. Synthetic stones will have no inclusions.

1. Evaluate only stereo microscopes. A stereo microscope is really two compound microscopes which view a point from slightly different angles providing a three dimensional, upright, and laterally correct view of the stone being viewed. This is absolutely essential in gemology. The two dimensional view that is provided by a standard compound microscope will not allow for inclusions to be seen, which is necessary to identifying the legitimacy and the species of the stone.
2. Consider only microscopes that are a minimum of forty power or greater. The higher power the microscope the more inclusions will be revealed in greater detail, making identification more likely. The eye piece of the microscope is interchangeable, and can be upgraded. Therefore, it possible to purchase a less expensive microscope with a better quality eye piece. This also makes it possible to upgrade just the eye piece of a microscope that the gemologist may have outgrown.
3. Consider a Hanneman stereoscope which has been recommended by noted gemologist, Ken Hamilton of Dartmouth, Nova Scotia. The Hanneman can be purchased for around $150. Also search the adds in the back of lapidary journals for used microscopes. When considering a used microscope, inspect the overall cleanliness as well as the condition of the lenses. Also check for play in the focusing adjustment, it should not move by itself under its own weight.
