As a follow up on the last newsletter/blog I would like to share with you some informations regarding natural colour diamonds and in particular about pink diamonds.
Natural colour diamonds are available in every colour of the rainbow and command dear prices due to the fact that they are extremely rare. Only one of every 10,000 diamonds mined is a natural colour diamond.
And even more so when we talk about natural pink diamonds. Out of the mine’s 20 million carat annual output, only 0.1% are classified as pink diamonds.
Natural fancy colour diamonds are continually setting records at auctions in the tens of million of dollars, as we saw happening at the last week auction.
Lucky these women who get to enjoy this wonders of nature!
Diamonds are made of pure carbon however we have a pink diamond when the diamond is subjected to enormous pressure and heat during formations which causes the crystal to distort. Such a distortion induces the diamond to absorb green light which creates the pink colour.
Colour strength, saturation and distribution are factors which determine the value of a natural colour diamond. This value increases with the intensity of the most prominent colour within the diamond.
Pure colours are the most desirable but most colour diamonds are a blend of two or more modifying colours. Usually, pink diamonds are modified by an orange, brown or purplish secondary colour.
GIA (Gemological Institute of America) grades colour diamonds by their intensity: Fancy light, Fancy, Fancy Intense and Fancy Vivid.
Pink diamonds, being so rare, have been found only in a few places across the world. The "Golconda" region in India and the "Minas Gerais" region of Brazil produced the majority of remarkable diamonds between the 17th and 18th century.
It is estimated that an astonishing 90% of the world’s pink diamonds are found today in Western Australia in the famous “Argyle Mine", which is also renown for the production of champagne, cognac and blue diamonds.
Pink diamonds have been discovered also in Borneo, Brazil, Russia, Canada and, occasionally, in Tanzania and South Africa.
It might be interesting to know that, according to the GIA, more than 80% of pink diamonds display fluorescence. Fluorescence is the reaction of a diamond to UV light and usually not a good factor in colourless diamonds.
Pink diamonds varied in colour from a delicate pastel to a deep raspberry. Pink is the ultimate feminine colour and it is identified with romance and love.
There exceptionally rare diamonds have been loved by Hollywood Stars for a long time and, nowadays, pink diamonds are favoured by collectors and connoisseurs all around the world.
I love pink… Let’s get "pink crazy!"
