After that, private trade viewings of the diamond will commence in June before it travels to Copenhagen, Hong Kong and New York.
The Argyle mine accounts for 90% of the world's rare pink diamonds, yet over the last 32 years, just 12 carats of polished violet diamonds have been produced for its Tender.
