Where do we get diamond ? |
The word diamond comes from the Greek word meaning unbreakable. Diamond is the hardest natural material. Naturally occurring diamonds are formed over billions of years under high pressure and heat. They are brought to the Earth’s surface by volcanic eruptions. Diamond is the world’s most popular gemstone. Thats why people wear diamond as rings and necklaces. It is so rare, well suited to jewelery because they polish well and can be scratched only by other diamonds and is also used for industrial cutting and polishing tools. |
