Natural Blue Diamonds: Price, Rarity and Touch-up of Supreme Diamond

The blue diamond is a naturally occurring diamond with the same features as that of a colourless diamond. However, the presence of boron contaminates the original colour and structure of the diamond giving it a blue shade. Blue diamonds have a range of shades from light blue to deep dark blue, often with a slight mixture of violet, grey, or green. Blue diamonds are not made cosmetically or created artificially to get their colour but are rather found naturally in the earth’s bed with their original authentic blue colouring.

There are only a few places in the whole world where blue diamonds have been mined out of the earth’s crust, places like the Cullinan Mine of South Africa, the Golconda mines in India, and the Argyle mine in Australia. 

Blue diamonds have been a rare sighting throughout the history of the world and have been admired for their indefinite beauty and elegance. Because of the difference in its look, these gems are considered to be more supreme than any other diamond hence are often more expensive.

Origin of the Color of Blue diamonds

Blue Diamonds are authentic and are formed underneath the earth’s surface after billions of years of high pressure and temperature acting on carbon. The colour blue naturally occurs, without any artificial hindrances due to the presence of boron in the crystal lattice of the carbon structure. It is a common mistaken notion wherein blue diamonds are often confused with sapphire stones. It should be noted that sapphire gemstones are completely different entities which are from the corundum family.
