Corundum (such as ruby and sapphire) however are the most durable stones, measuring 8 on the Mohs Scale and considered ‘excellent’ for toughness. If you’re wondering which stones are best for everyday wear such as an engagement ring, sapphire, ruby and diamond are wonderful choices.
What is the toughest gemstone?
The diamond is the hardest gemstones, while talc is a very soft mineral. The scale by which the hardness of minerals is measured is the Mohs Hardness Scale.
What gemstone lasts the longest?
Peridot, one of the shortest-lasting gemstones (often degrading in hundreds to thousands of years), and diamond, one of the longest-lasting (degrading in millions of years), both will last much longer than the average or even the extraordinary marriage.

Diamonds are the hardest stones on earth with a 10/10 score. This gem will not get scratched by anything other than another diamond. Following the diamond is moissanite, ruby, and sapphire; all of these stones have a rating of 9.0 and above.
What gemstone Cannot break?
Any gemstone can break when dropped onto a hard surface like a tile floor, including a diamond. Some manmade stones, such as the Cubic Zirconia with a Mohs hardness of 8 or 8.5 or Moissanite with a Mohs hardness of 9.25, will resist scratches and chips better than most other gemstones.
What stone is the hardest to break?
Diamond is the hardest natural material in the world. However, it’s also brittle. Scientifically speaking, hardness measures the ability to resist scratching, nothing more. A gemstone’s overall wearability grade takes hardness into account.
What gem is stronger than a diamond?
Moissanite, a naturally occurring silicon-carbide, is almost as hard as diamond. It is a rare mineral, discovered by the French chemist Henri Moissan in 1893 while examining rock samples from a meteor crater located in Canyon Diablo, Arizona. Hexagonal boron-nitride is 18% harder than diamond.

Does tourmaline scratch easily?
First, Tourmaline sits moderately high on its level of durability. On the hardness scale, Tourmaline ranges from 7.0 – 7.5, making it scratch resistant to matters that fall at a lower number than 7. … If you’re well versed in testing specific gravity, the specific gravity of Tourmaline is 3.06.
Are sapphires harder than emeralds?
Sapphires have a hardness rating of 9 on the Mohs scale and are used in scientific instruments and as wrist watch crystal faces. Emeralds are an 8 on the same scale which means they are reasonably durable, but liable to cracking and scratching.
