Diamond is by far the hardest gemstone. Diamond can only be scratched by another Diamond. The MOHS scale above shows where different 

The hardest rock to find is Painite. A British mineralogist first found this rare gem mineral in Myanmar but at first, they thought it was a Ruby. It wasn’t until the 1950s until Painite was found to be a new gemstone. Since it is so rare, it can cost up to $60,000 per carat.

Let’s have a look at the hardness of different gemstones! It would be hard to gauge actually how hard a gemstone is simply based on the relative numbers on the Mohs Scale. Here are the Mohs hardness levels of various daily objects to give you a better picture: Masonry drill bit (for drilling tiles and concrete) 8.5 - 9. Steel nail 6.5. Glass 5.5.

Diamond is generally the hardest gemstone. But cubic zirconia (CZ) is another type of diamond that is not as hard as diamond. Cubic zirconia was 

While diamond is the hardest gemstone, its all-round durability is considered less than that of relatively softer gemstones, such as sapphires and rubies, which can garner higher prices due to their toughness.

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.

Hardness - Hardness may be defined as a material's resistance to scratching. The diamond is the hardest gemstone and the hardest substance known in nature. Nothing can scratch a diamond except

Even though ruby and sapphire (corundum) rate a 9, a diamond is many times harder. Chrysoberyl is the next hardest gem (Mohs hardness of 8.5) followed by topaz and spinel, which have a Mohs hardness of 8. Many gems including diamond even have a directional hardness where one direction or surface is harder than another.

The diamond is the hardest natural gemstone in the world and measures a ten on the hardness scale. Gemstones measured at a one can be easily scratched with 

Diamond is the hardest known natural mineral according to the Mohs scale. Its hardness depends on its purity, and the hardest diamond can only be scratched by other diamonds. Some blue color diamonds are natural semiconductors, some are electrical insulators, and the rest are electric conductors.

A gemstone is a piece of mineral crystal which, in cut and polished form, is used to make Most gemstones are hard, but some soft minerals are used in jewelry 

The Mohs Scale rates the hardness of gems and minerals on a relative scale of 1 (softest – Talc) to 10 (hardest – Diamond). Introduced in 1822, the scale
