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.

How long do Gorillas live? The 51 years old silverback Matze in Frankfurt Zoo (Â© Mathias Orgeldinger) At an age of 35 or more, gorillas show distinct signs of age. Old mountain gorillas often suffer from arthritis, which mainly damages the bones in their hands and feet. They also suffer from the loss of teeth as a consequence of periodontitis, so that they have a problem with feeding. It takes them longer to feed and to travel than the other group members.
