For a thorough analysis of a gemstone, several precision instruments are used to examine and measure the different aspects of a gemstone.

4  A binocular microscope is a dual eyepiece microscope that allows the gemologist a three-dimensional static view of the gemstone. With a binocular microscope, special lighting, such as a reflective and black background lighting, can be used to more carefully assess the parts of the gemstone.

4  The 10x magnification loupe is the hand-held jeweler's loupe with which most people are familiar. Because it is held by one hand, it leaves the gemologist free to rotate the stone freely and dynamically examine the different facets of the stone.

4  The Master Color Comparison Stone Set, is a set of standardized gemstones by which all other gemstones are assessed. Comparing gemstones to the master set leaves no guesswork as to the true color of the gem.

4  Examining the stones under short-wave and long-wave fluorescent lights allows the gemologist to detect colors visible under the lighting conditions but are not part of the basic hue of the stone.

4  The millimeter gauge and the computer aided measuring device provide the Independent Gemological Laboratory gemologist with the extreme precision necessary for accurate value judgment of gemstones.

4  The electronic balance provides precise and accurate weight measurements of stones and mounted jewelry.
