Ruby Vs Diamond Hardness

If you hit a diamond with a hammer it ll shatter into a dozen pieces.

Ruby vs diamond hardness. The higher the number the harder the mineral. Hardness indicates how resistant a gemstone is to scratches. Diamonds have steadily increased in value and show no signs of slowing. Ruby is among the second hardest gemstones.

You may know that diamond with a hardness of 10 is the hardest material in the gem world. A gemstone s hardness is a good indicator of how well it will resist scratches and abrasions. However there s an old saying among gemologists. However this doesn t mean that the ruby is not.

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. On the mohs scale of hardness the diamond ranks a 10 while the ruby ranks 9. Everyday hazards such as this make gemstone hardness an important consideration when designing and wearing jewelry. Diamonds are the hardest gemstones and rubies are the second hardest ones.

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. 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. 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 if you are looking for a durable piece of jewelry that resists better to scratching then the diamond is the right one for you.

The mohs hardness scale starts with talc at 1 being the softest mineral and ending with diamond at 10 being the hardest mineral. The pricing of diamonds can range anywhere from 1 000 to 40 000 per carat depending on clarity cut and color. As an example diamond 10 is about 4 5 times harder than corundum 9 which is about 2 times harder than topaz 8. The mohs scale is a not a linear scale.

And as many people know diamond is the hardest gemstone. Diamond ranks a 10 on the mohs scale of hardness whereas ruby is a 9. It is universally used around the world as a way of distinguishing minerals. 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.
