Frequently Asked Questions (FAQ) / Rarest Gemstone

What is the rarest gemstone?

Rarest Gems

The rarest and most expensive of all gemstones is red diamond. In fact there are only perhaps 20 to 30 red diamonds known to exist, and most weigh less than half a carat. When offered at auction, they typically sell for more than $1 million per carat. The largest red diamond known is the 5.11 carat Moussaieff Red Diamond, a trillion-cut diamond from Brazil. For more information see our article on the world's rarest gemstone.
