Pink Diamonds / Argyle Diamonds

Pink diamonds or Argyle diamonds as they are sometimes referred to are somewhat more readily available than Blue Diamonds, however, as mining continues and demand increases for this rare commodity, supply of the lovely pink diamond is gradually diminishing.

The main source of the deepest and most intense pink diamonds is the Argyle mine in Australia, hence the name Argyle diamonds. The Argyle mine releases around 65 pink loose diamond stones per year to tender with a weight range up to 1ct, and another 50 - 100 stones of 'good colour' weighing from 0.5ct. That is it for the whole world! This mine has been estimated to be operable only until 2019. Thus, it is no wonder pink diamonds are a rare and wanted commodity.

As with all coloured diamonds, pink diamonds / Argyle diamonds are graded according to the intensity of colour in each individual stone. Argyle Diamonds uses a scale from one to eight - one being the most intense colour and eight the lightest colour.

The 1 to 8 grading is then given an additional grade according to each individual diamond hue.
