Cullinan I is a 530.2 carats diamond and is the largest part of the original diamond. It is a pear shaped diamond. It is also called Great Star of Africa and is displayed at the Tower of London. The royal Scepter of England bears the Cullinan I.
Most of the diamonds appear to be colorless on the surface. Although, if one looks carefully, they may have undertones of some other colors like yellow and brown. This usually takes place when other elements get integrated into their atomic structure, when diamonds are getting formed. Thus, when it comes to clear diamonds, the more colorless they are, the higher is their grading and thus, the more expensive and rare they are considered to be. The grading of the clear diamonds starts from D, E, F and goes up to S-Z, with D being the most clear, rare and expensive. However, this grading does not work in case of the colored diamonds. They are completely different from the clear diamonds and in fact, come in well-defined "fancy" colors, like, blue, red, yellow, orange, green, purple and pink. These diamonds are considered rarer than rare and are thus, priced much higher than any clear diamond.
One of the best ways to compare real and fake diamonds is to see through them. You will see that a fake diamond is just like glass. In order to differentiate between the two, take a black pen and make two tiny dots on a white sheet of paper. Now, place a real diamond and a fake diamond over the dots. You will find that the real stone breaks off the reflection of the dot, which makes it impossible for clear perception. However, the fake diamond is made of glass, so you can see the dot clearly. Another test is the newspaper test. If you go to a shop to purchase diamonds, never look at them over the jeweler's white tray. Ask for a newspaper or a printed piece of paper. Place the diamond over the print and see through it. If you can read the alphabets or designs printed on the paper through the diamond, then it is a fake. Spotting vague black marks or spots also proves that the diamond is a fake. If your diamond is mounted, check the bottom. If you can see the bottom while looking at it directly from the top, then the stone is mostly a fake one.
