What is the strongest metal on earth?

tungstenIn terms of tensile strength, tungsten is the strongest out of any natural metal (142,000 psi). But in terms of impact strength, tungsten is weak — it’s a brittle metal that’s known to shatter on impact.

Are old diamonds more valuable?

The cost of old European cut diamond values will depend on several different factors. Since these diamonds generally have a higher carat weight compared to modern diamonds they are usually more valuable. In addition, because they are rarer than modern diamonds their value is increased.
