What’s the industrial diamond?

You might have been asked from somebody to buy a “diamond” as a gift.
When you hear “diamond” a lot of people image a shiny, hard, gorgeous, and costly gem stone.
It is said that “diamonds are forever”, but usually one’s economic power is not limitless.
Nevertheless, the attraction of diamonds is irresistible and beyond the description.
Diamond is a very mysterious material, and for that reason, there are many tragic stories about diamonds around the world.

Let’s come to the point. As you might know, diamonds are not used only for gems.
They are used for industrial parts for their hardness, chemical stability, high heat conductivity semiconducting, and surface characteristic.
Actually, more than 90 % of diamonds are used in the industrial field, like diamond tools (end mill, cutter, bite, indenter, substrate or etc.), semi conductor, medical equipment, heat sink and more.
Diamond is a versatile material with many possibilities. There will be many more ways to utilize diamond in the future.
