The Basics of VVS Diamonds. VVS, or very very slightly included, diamonds have small inclusions that are undetectable to the human eye. In fact, these inclusions are so small that they are difficult to see even with 10x magnification. Typically, VVS diamonds are split into VVS1 and VVS2 subcategories.
Now, over 100,000 western lowland gorillas are thought to exist in the wild, with 4,000 in zoos; eastern lowland gorillas have a population of under 5,000 in the wild and 24 in zoos. Mountain gorillas are the most severely endangered, with an estimated population of about 880 left in the wild and none in zoos.
1 Eastern lowland gorilla (Gorilla gorilla graueri) is slightly larger in size weighing up to 220 kg (484 lb) and darker in coloration than the western lowland gorilla. They live in the rainforests of central Africa.  Mountain gorilla (Gorilla gorilla beringei) is the largest and rarest of all three subspecies. Adult males may weigh over 227 kg (500 lb.) They are found at high elevations of the Virunga Volcano range that separates Zaire from Rwanda and Uganda.
