No, obsidian is not stronger than diamond. Diamond is the hardest known natural material on Earth, scoring a 10 on the Mohs scale of mineral hardness. Obsidian, on the other hand, is a type of volcanic glass and is much softer, typically scoring around 5 to 5.5 on the Mohs scale.
While obsidian is known for its sharp edges and has been used historically for tools and weapons, it is not as durable or strong as diamond. Diamond’s exceptional hardness makes it highly resistant to scratching and abrasion, which is why it is used in cutting tools and industrial applications.
In summary, while obsidian has its own unique properties and uses, it does not match the strength and hardness of diamond.
