GEMSTONE REFRACTOMETERS ARE USED FOR THE CLASSIFICATION AND QUALITY CONTROL OF GEMSTONES. THE GEMSTONE TO BE EXAMINED IS SIMPLY PLACED ON THE PRISM WITH A DROP OF CONTACT FLUID. THE REFRACTIVE INDEX OF THE GEMSTONE IS READ THROUGH THE OCULAR OF THE REFRACTOMETER. THE REFRACTIVE INDEX IS AN IMPORTANT PARAMETER IN CLASSIFYING A MINERAL OR GEMSTONE. EACH MINERAL HAS ITS TYPICAL REFRACTIVE INDEX, DUE TO ITS CHEMICAL COMPOSITION AND CRYSTALLINE STRUCTURE. OUR GEMSTONE REFRACTOMETERS ARE CHARACTERIZED BY THEIR PARTICULARLY SHARP IMAGE AND GOOD READABILITY.
