Understanding Australian Blue Diamonds. The Rarest of Blue Diamonds.

Rare Blue Diamond Investments

The Australian pink diamond mine sporadically yields blue, grey blue and violet diamonds. In fact, an Australian pink certified diamond can be considered the rarest of all diamonds on planet earth. To put that into perspective, for every 25 million carats of rough diamonds unearthed from the Australian pink diamond mine, only a single polished blue or violet stone is produced.

In more than 30 years of the prestigious Pink Diamond Tenders, just 12 carats of polished violet blue diamonds have been offered for sale!

Blue Diamond Colour Grades

Most natural blue diamonds are rare, but the diamonds from the Australian pink diamond mine are the rarest of all. It is estimated that for every 1.00ct of certified Australian pink diamond inscribed diamonds, there are 350ct of natural diamonds on the market. When you consider this diamond in general is 25 times rarer than a pink diamond, this fact alone makes a blue diamond a stand out in any investor’s collection.

Blue and violet diamonds typically are Type IIb and contain the presence of boron. The Australian pink diamond mine is the only known source of Type 1a hydrogen-rich Blue, Greyish Blue and violet Diamonds as well as the uniquely potent cornflower hues.
