This is the start of a new chapter for Argyle pink diamonds to ensure they maintain their value and investment potential as a finite, unrepeatable natural resource and achieve the status of outstanding heritage diamonds. Hats off to Rio Tinto Minerals. Get to know John Calleija (Calleija) and John Glajz (Glajz THG).
Rio Tinto’s Argyle mine has yielded the largest gem-quality white diamond in its 35-year history. The 28.84-carat stone, named Argyle Octavia for its octahedral shape, was discovered at the Australia-located mine last month. This discovery is a testament to the extraordinary Argyle orebody that continues to deliver these miracles of nature, even as it nears the end of mine life. The Argyle mine is set to close in 2020. The company will sell the diamond at a tender in Antwerp later this year.
