The Story Behind the Stone: The Pink Diamond

Pink Diamonds are Rare and Mysterious

Most diamonds range in color from white, to brown and yellow. The more intense the natural color or in the case of white diamonds the lack of color, the more rare and expensive the stone.

Colored diamonds are so much rarer than the colorless ones that the highest-quality pinks regularly command millions of dollars more per carat than a traditional rock.  With pink diamonds, the price increases exponentially in relation to the carat size. A .50 carat stone might retail for $50,000 while a 2 carat stone could sell for $500,000.

The majority of all pink diamonds mined come from one source in Australia, the Argyle Mine. Argyle Pink Diamonds are so expensive because of the very limited supply. The mine which produces 90 percent of the world’s pink diamond supply is scheduled to close this year.  It also supplies a large proportion of other naturally coloured diamonds, including champagne, cognac and rare blue diamonds. 

The Science Behind the Stone

A pink diamond is formed of only carbon like a white diamond, through millions of years in the kimberlite pipes of volcanoes.  Colored diamonds get their hues from trace elements present during their formation. Specific elements cause specific colors – nitrogen for yellow diamonds and boron for blue, for example.

So what element is behind the hue in pink diamonds?

Interestingly, nobody knows for sure. Unlike other colored diamonds whose color origins are known, pink diamonds are a mystery and to date, we don’t yet know what causes a pink diamond.

However, there are scientific evidences, showing pink diamonds contain high pressure graining that result in a compressed internal structure. This is called Plastic Deformation and scientists believe that this process is behind the origin of pink diamond’s color.

An Affordable Option

An enhanced pink diamond is a natural diamond that has been altered from its natural condition in order to improve its physical appearance and characteristics and/or minimize its flaws. Color enhancement treatments are the most common.  

Color enhanced pink diamonds start in the earth. They are earth grown over millions of years and mined, just like a natural fancy colored diamond. Unlike it's rare cousin, however, the color enhanced diamond goes through a treatment process which changes the tone of the diamond. This is a permanent and internal treatment; it is not a coating.

They have deep rich colors, from vibrant bubble gum pink, to a more earthy pink, to purplish or burgundy colors.

Generally, enhanced pink diamonds are sold at a lower price compared to their untreated or unenhanced counterparts.
