Our New Colour Grading Card for Pink Diamonds
This year, we are pleased to present our new colour grading card for that exceptional and rare diamond colour…. pink. This card is the third in our series, coming after the cards for champagne and yellow diamonds.

Like the others, this card was designed to assist you in your customer dealings. It will also help facilitate discussions about various tints of colour. The card differs slightly from the standard colour grades used by the GIA that range from Light to Intense and from Vivid to Deep Pink. This year, we have added secondary colours like purple or purplish. This shows just how rare pure pink diamonds really are in nature.

On the back of the card, you will find important information explaining how pink diamonds are formed and where they are found.

A 0.30 ct Radiant Cut Fancy Intense Purplish Pink Diamond

Today, we are presenting a cheeky little radiant cut pink diamond. The Gemological Institute of America (GIA) has given it a well-deserved Fancy Intense Purplish Pink grade.

Its clear cut, intense colour and good clarity make it an interesting stone that could also attract attention from collectors looking for rare pieces.

All about Natural Coloured Diamonds
Pink - A Lighter Red
When we speak of Pink, we are usually referring to a bright, intense, “hot pink”.

In English, on the contrary, Pink can refer to a type of carnation (the flower’s name has been referenced since 1573). “Hot pink” describes a bright pink, whereas “shocking pink” has become the trademark of the avant-gardist fashion designer Elsa Schiaparelli (1890 – 1973).

Pink and purple are also known as magenta, a colour associated with idealism, gratitude and compassion. In the world of fashion, it is regarded as a soft colour.

The World of Pink Diamonds
The Argyle Diamond Mine, located in the Kimberly region of north-western Australia, has been for many years the main source of pink diamonds. Although pink diamonds can indeed be found throughout the world, the Argyle Diamond Mine has the largest reserves.

Currently, more than 90% of these stones are mined in Australia. No one knows what the future holds, however, and according to certain forecasts, the mine could still continue to produce until 2019.
Famous Pink Diamonds
Famous diamonds often have a chequered past whether they have been given, sold, stolen or found.

Pink diamonds, like red diamonds, are particularly rare.

They continue to fascinate and their power of attraction is magical. Come with us on a journey to the world of famous pink diamonds.
Gemmology Corner
Diamond Colour: Pink
Pink diamonds are some of the world’s rarest precious stones. Their colour is caused by a shift in the diamond’s crystal lattice. Type Ia diamonds as well as a few type IIa diamonds can have this natural pink colour.

The main colour is often accompanied by modifying tints. This is why a pink colour may tend towards orange, purple or brown. Although Argyle Diamonds and the Gemological Institute of America (GIA) use two different colour grading systems, both of which are very helpful in trade and colour assessment, the GIA colour grading scale has become the industry reference.
