what Tools Do Gemologists use?
- Microscope: The microscope is used for gem identification and the identification of internal and surface characteristics. Gemstone grading is done at 10x magnifications, although a gemologist may view stones at much higher power to determine treatments and characteristics
- Loupe: A handheld magnification tool, the loupe is used for identification and grading in much the same manner as the microscope. If you are new to gemstone shopping, it is important to familiarize yourself with correct use of the loupe. Hold the loupe in your left hand close to your eye, and using gem tweezers, bring the gemstone up to the loupe until it is in focus. Learn to discern with your own eye and become a connoisseur of gemstones.
- Micrometer: Used for precise measurements, the gemologist will use a micrometer such as a Leveridge gauge to determine dimensions such as average girdle diameter, total depth, and length and width.
- Refractometer: Each gemstone will bend light in a particular way. The refractometer is used to measure the refractive index, or RI which is a key indicator of a gemstone’s identity as well as measure the optic sign.
- Spectroscope: Measures the amount and type of light absorption in a gemstone. The two types of spectroscopes used are diffraction grating and prism.
- Polarisope: Used to make determinations regarding the optic properties of gemstones, the polariscope is an asset when distinguishing natural gemstones from synthetics.
- Heavy liquids: Used to determine the specific gravity of gemstones. Gemstones immersed in heavy liquids must be un-mounted or “loose” gemstones for specific gravity to be determined.
