In science I am learning about gems metals and stones and I thought it would be more fun to post about than to write about it on paper.

Most gems are mined from these mineral deposits in Brazil, India and South Africa. The deposits are in tube like formations called diamond pipes. Heres a picture of one . Most diamonds are colorless and Colored diamonds are very rare.

There are forms of mineral beryl are really really valuable .The most famous form of beryl which is MY birthstone is the emerald! :)
There are gems that are not rare and they are not as durable as precious stones. These are called semiprecious stones. One semiprecious stone that is often confused with the Ruby is the red spinel. A famous red spinel is on the British Imperial State Crown. It is called the "Black Princes Ruby" Here is a picture of the crown. The big red gem in the middle is the red spinel.

Another kind of semiprecious stone is called Tourmaline. Heres a picture of it.
I thought this stuff was kinda neat too its Chrystalized salt called halite this is what it looks like. Anyways gotta go TTYL!
