Why diamond jewelry is so expensive

Even though diamonds are found abundant in some countries, the high price is because it is not very easy to find them on the surface of earth. in fact these stones came into formation by the extreme heating for over thousands of years. Extensive mining needs to be done along with the usage of high quality tools in order to separate the diamonds from the rocks that hold them. The mining companies and the miners charge huge prices in order to extract the most precious stone of all - the diamonds. Once the diamonds are mined, they are still far away from what we see at jewelry stores; these stones need to undergo multi stage processes so as to look invaluable. The value of this stone is checked by the 4Cs that are color, cut, clarity and carat. When a pure diamond undergoes all the stages and looks extremely luxurious, then one thing that you could be certain of is that all the four qualities have been achieved perfectly.
It's not a cake walk to first extract the pure diamond and then make it undergo various processes in order to get a beautiful stone which then becomes a part of a ring, or a necklace or a pendant or any diamond jewelry for that matter sake. So the price is certainly high.
