Pink Diamonds

Pink diamonds are both rare and highly sought after – factors which provide a constant boost to prices. Indeed, prices have increased by a factor of 100 over the past 25 years. As a result, pink diamonds have become of increasing interest for mid- and long-term investors.

A distortion, or deformation, of the crystal lattice in the diamond, known as ‘graining’, led to the formation of pink, purple and some brown diamonds. Diamond experts believe that this is a result of the extreme pressures that the diamonds were under as they rose to the surface of the earth. It is also believed that this pressure is the reason why many of the diamonds in this color range, especially pink and purple ones, often have a lot of impurities.

Pink diamonds are found either as a single color or with any of the following overtone colors; Purple, Purplish, Brown, Brownish, Grayish, Orangy, Brownish Orangy, and Brownish Purple.

The intensity grades of natural pink diamonds are Faint, Very Light, Light, Fancy Light, Fancy, Fancy Intense, Fancy Vivid, Fancy Deep and Fancy Dark.
Pink diamonds come from the Argyle mine in Australia, as well as from Brazil, Angola and other countries with each country's production providing different shades of pink. Most pink diamonds from the Argyle mine are smaller stones, with the discovery of larger stones, of 1.5 carats and more, for the most part at an end.

It is extremely difficult to find pink diamonds with very high levels of clarity. But as long as they do not have a harmful effect on the diamond, impurities in pink diamonds are regarded as reasonable.

Furthermore, pink diamonds typically feature growth lines in their crystal lattice that are frequently visible, and which can give them a slightly dim appearance in the center of the stone. It should be remembered that this is completely natural, and not considered an imperfection.


Natural red diamonds are the rarest of all natural color stones. So much so that fewer than 10 such diamonds are produced annually in the whole world.
