For most people, a diamond is the most precious and the most beautiful gem in the world. The value of a diamond is characterized by four main features. Those are clarity, weight, color and cut. Those are commonly known as 4c. In general, diamond is an allotrope of carbon. Carbon atoms are tightly packed in it what gives diamonds a tough structure. Naturally, among those inter atoms bindings, there are some weaker parts in particular directions thanks to which we are able to split them.
Making a clever usage of those parts allows the diamond-cutters give a row diamond possibly the best shape. Diamond-cutting is an art that began in ancient times and the example was given by the very nature. It revealed shining stones or polished by the water materials having a high gloss and expressive coloration. Today, diamond’s sparkle is known and admired by many lovers of gems and their beauty.

The red light which comes to the longest beam, refract the least whilst the shortest wave with violet light – the most.
