The Mohs scale ranks gemstones and minerals in hardness from 1 to 10. The lowest number 1 represents the softest minerals and 10 corresponds to 

Gemstone Hardness is a measure of how difficult (or easy) it is to scratch the surface of the gemstone. The hardest gemstones (diamonds, rubies and sapphires) get a rating closer to 10 on the Mohs scale, while the softer gemstones (amber, chrysocolla and pearl) are placed closer to 1 (see the entire Mohs index below).

The gemstone's hardness is important as it measures how well a gemstone on the Mohs scale can withstand wear. The hardness is essentially an indicator of how well a gemstone can keep its polish when scratched, this is of course an essential property for any material but due to the valuable nature of gemstones, it is extra important! Gem

Any gemstone that, is approximately the hardness of quartz (7) is said to be 7 in hardness, but if it tests between two of the minerals on the scale, it is expressed by 1/2. Thus a gemstone that tests harder than quartz but softer than topaz is said to be 7 1/2 in hardness.

To be considered a true “gemstone”, a jewel must have a certain “gemstone hardness”. Minerals with a Mohs hardness of 1 to 2 are considered soft

Mohs hardness scale is a chart that measures how resistant a gemstone or mineral is to being scratched or damaged when exposed to general wear and tear.

Gemstones come in varying hardnesses. By understanding the number associated with each stone, you can feel fully prepared to protect your jewelry. The experts classify gem 'hardness' using a universally accepted grading system called the Mohs hardness scale. To really grasp the concept, take a peek at the photo below.

Hardness defines the durability of the gemstone, the ability to retain its surface finish and polish. Moh’s scale is used to measure the hardness of a stone. It is a relative and not an absolute scale and created to compare the hardness of gemstones. This scale rates hardness of minerals on a scale of 1 to 10.

The Mohs scale of hardness is a qualitative scale ranging from 1 to 10 that describes the hardness of gemstones and minerals. It’s often used in geology but other industries such as milling, or fashion and apparel will refer to it frequently.

Mohs Scale Hardness Developed by the German geologist Friedrich Mohs it is currently the most commonly used scale of hardness. It is based on whether a mineral can scratch another mineral, if it can it means it has a higher hardness. If it can't it means it has a lower hardness. If you repeat this for many different minerals you can form a list.

Other factors aside, peridot, quartz (including amethyst and citrine), tourmaline, all the jaspers and agates, most garnets, and topaz are some common stones generally considered hard enough for setting in rings and bracelets, with hardnesses ranging from 6-1/2 to 8.

With a Mohs hardness level between 6.5 to 7.5, depending on their quality, Tsavorites have just begun their run of fame in the world of gemstones. So these are the gemstones that are famous around the world for their astonishing hardness level.

In the Mohs scale, a gemstone's hardness measures how well it can resist being electroformed in the electroforming bath and the wear and te the gemstone. In a gemstone, for instance, hardness is an indicator of how well it will keep its polish when scratched. Although vital for any material, the precious nature of gemstones makes it that

The Mohs scale of mineral hardness was created in 1812 by German geologist Freidrich Mohs and it helps us to identify different types of minerals and gemstones 

The Mohs gemstone hardness scale is based on the ability to scratch one more natural mineral. The models of material cast-off by Mohs are all minerals. These gemstones are chemically pure in natural substances. Gemstones are composed of one or more minerals. As the natural material that is commonly recognized, diamonds stand at the top of the

Way back in 1812, a German geologist by the name of Friedrich Mohs (big surprise, right?) created a “scratchability” hardness scale. The less “scratchable” a
