Basically, a diamond is a beautiful gem. So we might say that its beauty makes it desirable and valuable. The diamond is also the hardest substance known to man, and this hardness is very useful. So this also makes.
The diamond valuable. Now why should one diamond be more valuable than another? Well, the diamonds that are offered for sale in jewellery,may vary considerably in colour and quality. They occur in all colours of the rainbow. Some colours are rarer than others. The highest values are placed on those tinged with red or blue, and clear, colourless diamonds. Another factor which has an important bearing on value is purity. Diamonds may be as pure as a drop of water, or may show defects from a small pinpoint to a large flaw.
There are many diamonds that have been so valuable they have actually played a part in history. The most famous of these is the Koh-I-noor (Mount of Light), which has the longest history of any diamond in the world. Possession of this stone was so greatly desired by the rulers of Asia that practically all of the conquests of India from 1400 to 1828 were the result of it!
The Hope, an unusually blue diamond weighing about 44 carats, has also passed through many hands. The Hope is said to bring misfor- tune to all who possess it. Other famous diamonds are the Orloff, a former Russian crown jewel; the Regent, now in the Louvre in Paris; and the Cullinan, whose pieces are in the British crown and sceptre.
Inferior grade diamonds are used in industry. Many arc manufactured into diamond-grinding wheels which are used to sharpen tools and to grind lenses. Industrial diamonds arc also used in drills by mining companies to drill through rock.
