What is the third hardest gems?

Answer 1

: Diamond is the hardest gem.

:

: It is the only gem to rank a 10 on the 1 to 10 Mohs hardness scale. When we talk about "hardness," we're talking about a gem's ability to withstand scratching. As the hardest gem, diamond can scratch, or cut, any other stone, but only a diamond can scratch a diamond. : After diamond, the next hardest gem is sapphire. Even though sapphire ranks 9 on the Mohs scale, it is not nearly as hard as diamond.

: Neither diamond or sapphire, however, is the *toughest* gem. That distinction belongs to nephrite, a type of jade. Toughness measures resistance to breaking, and nephrite jade is tougher than both diamond and sapphire.

Answer 2

The hardest naturally occurring gemstone in the world is the diamond. It is renowned for its exceptional hardness and is assigned a maximum hardness of 10 on the Mohs scale of mineral hardness. The Mohs scale is a commonly used system that ranks minerals based on their scratch resistance. Diamonds are composed of carbon atoms arranged in a crystal lattice structure, which contributes to their remarkable durability and makes them the hardest known substance.
