Interesting Facts about Coloured Diamonds |
 |
|
 |
Diamonds are considered to be signs of romance, status, and a luxurious lifestyle. Although transparent diamonds have been used for centuries in jewellery and people around the globe have been purchasing them with great interest, new varieties of colourful diamonds are now being made available on the market. These varieties have gained a lot of popularity due to their unique nature and beauty. There are many different features of these colourful gems.
How Coloured Diamonds are formed
Just like clear ones, these colourful gems are developed by the intermingling of carbon atoms around 150 kilometers deep inside the earth. These stones are developed due to enhanced heat and pressure which is found in the earth’s mantle. When, along with carbon, certain other elements found in the depth of the earth are intermingled with carbon atoms, different colours are produced, which gives such a marvellous and attractive look after cutting and polishing.
These coloured stones are very rare since they are developed in special conditions which are scarce. Their occurrence is 1 in over 10,000 transparent diamonds. Different colours are generated due to the presence of different elements. For instance, the yellow colour is produced if nitrogen is present during the development of these stones under extreme pressurisation and heat.
Blue colour, on the contrary, is produced due to the presence of boron reacting with carbon. There are some specific places in the world from where this substance is taken out, like Pretoria, South Africa.
Pink diamonds are also able to form. These diamonds are very rare and found in some specific regions like Brazil, Tasmania, India and Australia.
Brown coloured diamonds are formed due to intense compressions. They are found more than pink coloured stones and are mainly discovered in Australia. The other regions where they are present are Siberia and Africa.
Besides natural coloured substances, there are several varieties which are developed artificially. The colours can be manipulated by gemologists and hence fancy varieties are produced. In order to change the colour, irradiation is performed which is followed by heating. This process can alter the colour of gems partially or completely, depending upon the process used to alter their colours.
Last but not least, besides altering the natural colour of diamond, gemologists can make synthetic colours as well. These colours are much more attractive and do not alter the shine of the stone. These newly developed gems are produced in various shapes and designs. |
