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 is the toughest gemstone?
A stone’s Mohs rating provides a measure of its scratch resistance to other minerals. Diamond is known to be the hardest and can scratch any other stone. Talc is the softest. Reference minerals in between include gypsum, calcite, fluorite, apatite, orthoclase feldspar, quartz, topaz, and conundrum.
What gemstone is harder 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.
What is the strongest thing in the world?

Can you melt a diamond?
In the absence of oxygen, diamonds can be heated to much higher temperatures. The ultimate melting point of diamond is about 4,027° Celsius (7,280° Fahrenheit).
What are the hardest and second hardest gems?
Sapphire is also only used to describe the gem variety; otherwise it is simply called Corundum. Corundum is a very hard, tough, and stable mineral. For all practical purposes, it is the hardest mineral after Diamond, making it the second hardest mineral.
Which gems should not be worn together?
They should not be combined. For example, emerald and ruby; yellow sapphire and diamond; and pearl and blue sapphire should never go together. To find out if the gemstone has any defect, seek the services of a trained person or a gemologist.
Which is harder diamond or emerald?
Emeralds are actually a fairly hard gemstone when measured on the Mohs scale of hardness. Diamond is a 10, corundum is a 9 and beryl (the gem family that emerald is from) is approximately an 8. Aquamarine, another member of the beryl family is a true 8 on the scale but emerald comes in closer to 7 1/2.
What is the rarest gem on earth?
Painite : Not just the rarest gemstone, but also the rarest mineral on earth, Painite holds the Guinness World Record for it. After its discovery in the year 1951, there existed only 2 specimens of Painite for the next many decades. By the year 2004, there were less than 2 dozens known gemstones.
Which gemstone is most powerful?
Diamond. It is not only one of the most expensive gemstones, it’s the strongest one.

What is the closest stone to diamond?
Moissanite is a form of silicon carbide and is usually produced synthetically. Because of its hardness (9.5 on the Mohs scale), it is perhaps the diamond imitation material that is closest to the real thing in terms of durability.
What is the second hardest gem on earth?
Moissanite: The Second Hardest Mineral in Nature after Diamond.
What happens if you smash a diamond with a hammer?
While diamonds are the highest rank of hardness (ranking 10 of 10 on Mohs Scale of Mineral Hardness) they only rank fair-to-good when evaluating mineral toughness. So, while diamonds are essentially unable to be scratched by anything other than another diamond, diamonds can, somewhat easily, be smashed by a hammer.
Can I wear emerald everyday?
Yes, emeralds can be worn every day albeit with utmost care. This is because, even though emeralds are fairly durable, they are not immune to damage. If they are handled roughly or receive a sharp blow, they can chip and even break. It is also important to keep in mind that emeralds typically feature inclusions.
