Gem stones are graded similarly to Diamonds by clarity,color,size,cut.
Grading is with a 10x loupe.
Normally you will see the inclusions in Emeralds called a (Garden) clouds can be caused by inclusions,treatments,oils,bad cuts,etc...
Brazile, in the past produced some gem quality Emeralds -Key word is Gem Quality.
There are gems and then there are stones and then there is rough (un cut and un polished stones)
Color and clarity and size are key to prices of emeralds.
Hope this helps
