Ruby Vs Diamond Hardness

And as many people know diamond is the hardest gemstone.

Ruby vs diamond hardness.

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. You may know that diamond with a hardness of 10 is the hardest material in the gem world. The mohs hardness scale starts with talc at 1 being the softest mineral and ending with diamond at 10 being the hardest mineral. Only a diamond can scratch a diamond.

Sapphire ruby and pure corundum are α alumina the most stable form of al 2 o 3 in which 3 electrons leave each aluminium ion to. On the mohs scale of hardness the diamond ranks a 10 while the ruby ranks 9. Diamonds have steadily increased in value and show no signs of slowing. Rubies have a hardness of 9 0 on the mohs scale of mineral hardness among the natural gems only moissanite and diamond are harder with diamond having a mohs hardness of 10 0 and moissanite falling somewhere in between corundum ruby and diamond in hardness.

Hardness indicates how resistant a gemstone is to scratches. Diamonds are the hardest gemstones and rubies are the second hardest ones. The higher the number the harder the mineral. The pricing of diamonds can range anywhere from 1 000 to 40 000 per carat depending on clarity cut and color.

Ruby is among the second hardest gemstones. Because the mohs scale is a relative scale the difference between the hardness of a diamond and that of a ruby is much greater than the difference in hardness between calcite and gypsum. However this doesn t mean that the ruby is not. However there s an old saying among gemologists.

A gemstone s hardness is a good indicator of how well it will resist scratches and abrasions. So if you are looking for a durable piece of jewelry that resists better to scratching then the diamond is the right one for you. Which gem is better in terms of hardness between ruby vs diamond is a clear answer in this category. Diamond ranks a 10 on the mohs scale of hardness whereas ruby is a 9.

The mohs scale is a not a linear scale. If you hit a diamond with a hammer it ll shatter into a dozen pieces. 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. Instead it ranks gems on a relative scale based on their scratch hardness so although corundum ruby or sapphire is a 9 a diamond at 10 is many times harder.
