Ruby Vs Diamond Hardness

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.

Ruby vs diamond hardness.

However there s an old saying among gemologists. Diamond ranks a 10 on the mohs scale of hardness whereas ruby is a 9. Hardness indicates how resistant a gemstone is to scratches. However this doesn t mean that the ruby is not.

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. Diamonds are the hardest gemstones and rubies are the second hardest ones. And as many people know diamond is the hardest gemstone. 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.

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. As an example diamond 10 is about 4 5 times harder than corundum 9 which is about 2 times harder than topaz 8. A gemstone s hardness is a good indicator of how well it will resist scratches and abrasions. Which gem is better in terms of hardness between ruby vs diamond is a clear answer in this category.

Diamonds have steadily increased in value and show no signs of slowing. The mohs scale is a not a linear scale. You may know that diamond with a hardness of 10 is the hardest material in the gem world. 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.

The mohs hardness scale starts with talc at 1 being the softest mineral and ending with diamond at 10 being the hardest mineral. The higher the number the harder the mineral. 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. 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. It is universally used around the world as a way of distinguishing minerals. If you hit a diamond with a hammer it ll shatter into a dozen pieces. On the mohs scale of hardness the diamond ranks a 10 while the ruby ranks 9.
