What is the Most Precious Gem in the World?

When it comes to price per carat, the jadeite is the most precious gem in the world as it costs over $3 million per carat. This value is given by the rarity of the gem. However, value can also be given by the size of a gem stone. A good example of that is the largest pearl in the world which weights six tons and is worth $301.197 million.
