Diamonds and the Mohs Scale - Valentin Magro

The Mohs Scale of Mineral Hardness determines a stone's resistance to scratching. A mineral such as talc may be scratched by anything matching or exceeding its hardness. The higher on the scale a stone is, the less vulnerable it is to abrasions. Diamonds are at the far end, the pinnacle of hardness. At the same time, diamonds are admired for how its cuts draw out its aesthetic …

Mohs Hardness Scale: Testing the Resistance to Being Scratched

What is Mohs Hardness Scale? One of the most important tests for identifying mineral specimens is the Mohs Hardness Test. This test compares the resistance of a mineral to being scratched by ten reference minerals known as the Mohs Hardness Scale (see table at left). The test is useful because most specimens of a given mineral are very close to the same hardness.
