An inclusion is a particle of foreign matter found within a gemstone. Inclusions can be another mineral, a liquid or a gas. Inclusions decrease the value of a diamond when visible with a 10X loupe, but are a means of identification in Ruby, Sapphire and Emerald in order to separate synthetic stones from natural ones.
