The Letlapa Tala Collection - Five Extremely Rare Exceptional Blue Diamonds

The Letlapa Tala Collection - Five Extremely Rare Exceptional Blue Diamonds - Monroe Yorke Diamonds

Humans are fascinated by things that are unique, rare and beautiful.  We travel the world to see sites such as the sails of the Sydney Opera House, the wildly romantic floating city of Venice, or the Eiffel Tower, the icon of the city of love, Paris.  We flock to these sites to view the great beauty of rarity.

This same concept has made diamonds so captivating for humans for thousands of years.  Humans have been drawn to diamonds for their beauty and rarity.  While every natural diamond is unique and one of a kind, there is no diamond more captivating than a natural blue diamond.  Blue diamonds are incredibly rare and have only been unearthed at the Cullinan mine in South Africa, Golconda mine in India and Argyle mine in Australia.  

Natural white, yellow and pink diamonds are formed under a combination of extremely high temperature and pressures about 150km below the surface of the earth. The beautiful natural diamonds we wear today were formed millions or even billions of years ago.

These diamonds are then brought to the surface by deep and powerful volcanic eruptions.  These are special kinds of very violent eruptions that occurred thousands or even millions of years ago.  We have not seen eruptions of this nature in recent history. 


Why are blue diamonds rare?

Blue diamonds are believed to form three times deeper than other diamonds.  Blue diamonds contain the chemical boron.  Scientists believe that this boron was carried down earth’s tectonic faults down ancient ocean floors.

The most famous blue diamond – the Hope Diamond

The hope diamond was unearthed in ancient Indian from the Kollur mine.  The stone was from the famous Golconda Diamonds.  The earliest records of the movement of this diamond start from 1666.  Currently the Hope Diamond is in exhibition at the National Museum of Natural History – Smithsonian Institute in Washington DC.
