As Marilyn Monroe said, “Diamonds are women's best friends. That is why almost every woman has a weakness for diamonds and diamonds. Diamond is made of pure carbon and gemstones. This gemstone, which has a hardness of 10 on the Mohs scale,is the hardest material in the world. This means that no other material can scratch on it, but it can scratch all the materials.The reason why the diamond looks so bright and glamorous is the light refractive coefficient. Because the amount of light reflected by the diamond is greater than the amount of light it enters, the stone looks quite bright. It wouldn't be wrong to say the diamonds are dropping the rainbow. When you look at the diamond because you have the ability to divide the light into colors, you can see that white light is divided into rainbow colors.
