when they are married to show their love to their wife. Everyone knows that
diamond is the most expensive minerals in the world, and it is also the hardest
and colorless mineral. that's why males give it to their wife as gift, because
it symbolic last forever. However, diamond is not colorless. Diamond could also
have color such as yellow, blue, and pink etc.
First of all, many people believe diamond
was found from coal, but “Coal has rarely
played a role in the formation of diamonds. In fact, most
diamonds that have been dated are much older than Earth's first land plants”. [1]
There are 4 ways for diamond to be formed, deep source eruptions, subduction
zone diamond, asteroid impact diamonds, and diamonds formed in space. [1] Most
of colored diamond came from deep source eruptions, and while they formed deep in earth, the environments around them affect their structure and causes variety of color.
The different structure in diamond natural colored the diamond. Colorless diamond formed with pure carbon molecule, but when the carbon molecule bonding with other atoms, colored diamond produced. For example, when diamond is formed, boron might bonded with carbon, because it`s size is similar to carbon. When boron bonding with carbon molecules, blue diamond will be produced, and if it is nitrogen, orange diamond will be produced.[2]
The color of diamond might also changed by the temperatures and pressures. While diamonds voyage to the surface of earth, the high temperatures and pressures causes the crystal lattice distort, which causes diamond to have red or violet color. Green diamond is the most special one, which formed by absorbed the radiation when it was in deep earth.
Variety kind of diamond[3]
Because of the rarity, natural colored diamonds are extremely expensive.One of the famous nature colored diamond is the Hope Diamond, because of the legend behind it, and it worth 350 million dollars.[4]
