On mohs scale diamond s hardness is 10 1 is the softest and 10 is the hardest grade while its absolute hardness is 1600. It is possible to buy inexpensive kits with a sample of each of these to test minerals in the field. Water hardness testing of the water in the black diamond system happens regularly with larger scale testing occurring twice each year. Black diamonds are tougher than any other diamond.

They are a 10 on the moh s hardness scale and their dense polycrystalline structure makes them more difficult to cut and polish than colorless diamonds. The mohs scale of mineral hardness m oʊ z is a qualitative ordinal scale characterizing scratch resistance of various minerals through the ability of harder material to scratch softer material. So in terms of absolute hardness it is 4 times harder than corundum the next hardest substance from which rubies and sapphires are formed. Friedrich mohs a german mineralogist developed the scale in 1812.

The mohs scale is based on 10 reference minerals that have hardness 1 to 10 as follows. Do not use steam or ultrasonic cleaners which could cause damage. Created in 1812 by german geologist and mineralogist friedrich mohs it is one of several definitions of hardness in materials science some of which are more quantitative. Part of the results of those tests provide us with the hardness level of our water which residents with water softeners need to know.

The care and cleaning of black diamonds is the same as for any delicate gemstone. He selected ten minerals of distinctly different hardness that ranged from a very soft mineral talc to a very hard mineral diamond. If you check granite hardness on the mohs scale you will find it harder than marble and softer than quartzite.
