Natural pink diamonds of over one carat are exceptionally rare! The Argyle mine here in Australia was estimated to be the source of more than 90% of the world's pink diamonds during it's 37 year operation and in that period, very few pinks weighing a carat or more were sold each year. On average, only 15-20 such diamonds were offered annually through the Argyle Pink Diamonds Tender sales and it's unlikely that there would have been more than 100-200 pinks in the 1 carat plus size produced globally in any given year. With the mine now closed, that number has been dramatically reduced.
Here at Mondial, we currently have an impressive 1.03 carats, square radiant cut pink Argyle diamond, set in a ring, which has been graded by the GIA as "Natural Fancy Intense Pink" (# 5111432100). This diamond was originally purchased from the Argyle offices by Mondial's founder, Fred Neuman, who was attracted to it's unusually large size and intense colour. The diamond still has the original certificate which details the stone as weighing 1.07 carats, colour "5BP" and clarity SI2.
Mr Neuman identified that the diamond could be repolished with the loss of very little weight, in order to bring out more of the Pink colour. So he arranged to have that done and the result is the very impressive - and comparatively affordable diamond which features in the ring coded - G15687.
The ring is crafted in 18 carat white and rose gold and claw set on each side of the Argyle pink diamond with one trapeze cut diamond, total weight: 2 = 0. 36 carats and bead set on the side profile with round brilliant cut diamonds, total weight: 18 = 0.06 carats, colour F, clarity VS.
