Hardness of gem correlate closely to the wear resistance,it is most important factor of the value of gem. Hardness pencil is used for scratching the rough gemstones. If there are scratches, the gemstone hardness is lower than that hardness marked on the pens. Mohs Hardness from 1 to 10. It includes:1, Talc 2, Gypsum 3, Calcite 4, Fluorite 5, Apatite 6, Feldspar 7, Quartz 8, Topaz 9, Corundum 10, Diamond

Common gemstone varieties can be used for routine appraisal teaching, facilitating students to understand some common gemstone characteristics. Also used for jewelry inlay, gemstones have a variety of colors and shapes, and are also suitable for students’ jewelry inlay classes

This set of specimens includes natural gemstone specimens, optimized gemstone specimens, and synthetic gemstone specimens. Each gemstone has obvious and typical internal and external characteristics, making it easier for students to understand the microscopic characteristics of gemstones

The microscope is a great tool for separating natural from synthetic, imitation and assembled gemstone and for quality grading of both diamonds and colored stone. The Model of FGM-R1-15 is a vertical binocular stereoscopic continuous zoom microscope, which can observe objects clearly and intuitively, and can fully reflect the internal characteristics and surface characteristics of gemstone specimens.
