It has always been said that diamonds are forever however the Argyle pink diamonds may not be. The supply of economically viable pink diamonds is approaching exhaustion. & the Argyle pink diamond mine is set to close in 2020. Pink diamonds are the rarest in the world & the Australian mine produces more than 90% of the world’s supply. It is a loss of a beautiful natural resource which is unique & special to our nation. The closure may lead to alternatives such as synthetics being used or the rise of different colours. It may also lead to savvy investors acquiring some now as a future investment. A wise tip to any prospective investors is to make sure you have the certification paperwork on hand.
