With the foresight that the industry would require ongoing tracked value growth, ADI began tracking the growth of select diamonds from August 2019 and having them revalued every year from there on out.

Buying pink diamonds certified by the Argyle mine for your self-managed super fund?

Since 1985, approximately 90% of global production of natural pink diamonds have been extracted from the Argyle’s diamond mine in Western Australia. However, only a select number of these pink diamonds were retained, polished and certified as the highest quality examples of coloured diamonds to come from the Argyle. The rest were sent to auction and sold as ‘seconds’ because these are better suited to jewellery and showed little investment potential compared to the high standards set by the Australian pink diamond mine.

The other 10% of pink diamonds mined and sold globally, that is those not sourced from the Argyle mine, are predominantly from Africa, India and Brazil, with a small amount of pink-purple that have been extracted from mines in Canada and Russia.

According to extensive research by the GIA, all pink diamonds fall into two DNA classes, Type Ia and Type IIa. pink diamonds from the Argyle mine are almost exclusively Type Ia and all others are predominantly Type IIa. When considering purchasing a natural pink diamond, the best option is the rarer Type Ia pink diamond from the Western Australian pink diamond mine; as these diamonds exhibit the unique qualities to look for in an investment. The relative rarity of such pink diamonds results in a premium that being placed upon an Australian pink diamond. The best colour grades to consider have a saturation of 1 – 6, in colours Purplish Pink (PP) and Pink (P), followed by Pink Rosé (PR) since these exhibit a distinctive pink hue visible to the naked eye. When considering the shape of a diamond for investment, it is wiser to choose from a traditional fancy cut such as an emerald, oval, pear, marquise, radiant, cushion, heart, princess or round brilliant shape diamond, as these are considered more desirable, are better known, and may return a greater profit over one of the non-traditional modified fancy shapes.
