Rarest Gemstone 

Hello gem lovers! 

Have you ever wondered what the rarest gemstone is in the world? Or most expensive?


It's a bit difficult to truly know the rarest crystal in the world. We may never know for sure what the rarest gem in the world is because there could always be a source that simply hasn't been found yet.

Currently, musgravite is one of the rarest of all gem species. Musgravite was first discovered in Musgrave Ranges, Australia, and later found in Madagascar and Greenland. Musgravite is a member of the taaffeite family of minerals and the separation between the two is based on magnesium content.

What makes it so rare?

Musgravite is considered the rarest crystal in the world. There were only eight gem-quality stones mined in 2005. Musgravite is valued at nearly $35,000 per carat. It ranges in color from translucent olive green to a greyish purple. 


What is the rarest and most expensive gem in the world?

The rarest and most expensive gem in the world is a Red Diamond. Out of all the diamond colors in the world, red is the rarest, even rarer than pink diamonds. The red diamond can cost as much as $ 1 million per carat, and most of the known specimens are less than half a carat!
