Argyle Blue Diamonds
Blue diamonds are considered to be the rarest coloured diamond apart from Red. One of the only recognised sources of natural Blue diamonds and THE ONLY source of rare blue-violet and violet diamonds was the Argyle mine in Western Australia, which ceased production in November 2020.
So rare are Argyle’s uniquely hydrogen-rich cerulean spectrum, that all the GIA graded blue and violet diamonds offered in the history of the Signature Tender put together, would weigh just a touch less than the weight of the famous Hope diamond (45.52cts)
Argyle Blue diamonds are often referred to as Blue-Grey or Blue Violet diamonds. Unlike all other blue diamonds in the world - which get their colour from minute traces of boron - Argyle Blue diamonds contain small traces of hydrogen, which is the cause of the Violet or Blue-Violet colour: the hallmark of the rarest and most valuable of the Argyle Blues.
The blue diamonds from Argyle are never just blue and always receive a lab grading which includes a modifying colour of grey or violet.
”Once in a Blue Moon” was a curation of the very last blue and violet diamonds to emerge from the iconic Argyle diamond mine. So rare are these treasures that the Once in a Blue Moon’s collection of 24.88 carats was curated over the course of more than three years.
