Organic Gemstones

Most of the gemstones are made out of mineral materials. However, there are some of them made from organic materials which means they are made from living things. Here are interesting things about these. 

Pearl

It is known to be the queen of all the gems. This gem had a lovely soft glow in its natural state. A perfect pearl only needs to be drilled fr stringing to be shown off beautifully. A pearl results from an irritation to an oyster or some other shellfish. When the oyster has an irritating object within its body, it gradually builds over it a lustrous coating called nacre, or mother-of-pearl which is a shell lining material that shellfish normally develops. As it covers the irritating object, layer by layer, it builds up a pearl. 

Coral

Coral is used for different kinds of accessories such as necklace, bracelets and other beaded types like curtains. The coral is a hard, stony skeleton built by a small sea animal called a coral polyp. A coral does not have only one color but also red, pink white and black. These are usually the one used as gems.

Jet

A very hard and very black special variety of lignite or brown coal is know as the jet. This gem is velvety black, light-weight and warm to touch. During the Victorian era, when people dress for a mourning ceremony, Jets were famous gemstones. However, nowadays it is not limited only for this purpose of going to funerals.

Amber

Amber is a hardened resin that once oozed out of prehistoric trees. It is now found under layers of sand and gravel. For many years, amber has been a popular material. Most amber are purely transparent but could contain perfect specimens of prehistoric insects that were trapped in the resin thousands of years ago.

Origin of the Domestic Dogs

Most scientists think that the wolf is the main origin of the domestic dogs we find nowadays. However, not only the wolves but also the jackals, coyotes and even the dingoes. One example are the dogs in India which look like the local jackals. 

The question was, how were they able to control these wild animals and became their buddies? We all know about the cave people, who lived inside the caves for the rest of their lives, hunting using stones and spears. Often times, these animals would live beside their caves. When these people live, they scavenge for leftover meat. However, some are too cruel and kill these animals, instead. Sometimes, they also play with the young ones. 

Years have passed and they got used to it. Their puppies are know grown to be more affectionate to the human beings. They became hunting partners of the humans. They give each other a part of what they were able to catch. Crossbreeding began to happen.

Most famous foxes:

1. Red Fox

The red foxes of America were unlike the foxes that were found in Europe, Asia and North Africa. However, they have similar behavior and looks. They have a sharp and ling nose and they are covered with their golden red coat. These foxes can be also affected with rabies.

2. White Fox ( Arctic)

This kind of fox lives in the most northern part of the world. Its ears are rounded and shorter than ordinary foxes. When summer arrives, their coat turns from whit to dull, gray brown coats. When fall arrives, some became gray blue and some are really white. During the time of summer, they hunt on rodents and lemmings. They also follow polar bears if they spot one to wait for whatever it kills from the sea and tries to share it with them.
