Which is the most valuable mineral in the world?

The most valuable mineral is the Red Diamond. It is possibly the second rarest mineral on Earth after Painite. With a deep purplish red tone, the red diamond is famous for being one of the most valuable, expensive and, of course, beautiful minerals ever.

Its price is over $2 million per carat. One mine in Australia produces a small number of treated red diamonds each year that routinely auction for millions of dollars each.

blood diamonds and red diamonds are not the same. blood diamonds is a term used for a diamond mine in a war zone and sold to finance an insurgency.

WOW! I did not know that! Thank you. I do have the 8th mineral, a diamond from my country Kenya.

trumax, it's a metal and a mineral.

You're supposed to go back 6 years to when this question was first asked to get the correct answer at that time.

gold is not a mineral

Martha Prefontaine

Poorly worded. Should say which of these gemstones is most valuable.

David de Tremaudan, I have heard of diamonds being used for cutting. I checked <<50 Uses of.com/earth>>. It lists dentist's drills and covers for lasers and X-ray machines, as semiconductors in computers and other medical and industrial uses. I am sure it has been used for payment for services but am unsure it was ever a standard for currency, like gold. Thank you, Christine, James's wife

Richard Heth, I wish people would stop buying them. They're worthless to me. Beautiful, but not worth the money people pay.

Cindy Ursan

WOW that’s beautiful!!!!

In reality, diamonds have a singular value as jewelry. Gold on the other hand has application throughout electronics, industry, and holds the monetary value of economics around the world. It’s rarity and it’s application to all it’s placement in the world makes it more valuable than any of the gems listed here.
