1-10 Mohs Hardness Tester, Mohs Hardness Test Kit (10 Pieces), with Storage Box, Made of Stainless Steel, Suitable for Tiles, Flooring, and Glass.

Product description Indirect visual estimation method, the hardness of the gemstone can be reflected in the smoothness of the facets and the sharpness of the edges after processing. Under a magnifying glass, you can see that the facets of gemstones of varying hardness are smooth, flat, and have sharp edges. The indirect visual inspection method is a non-destructive approximate hardness identification method.
