There are structural constraints that will limit the production of rare pink diamonds and contribute to a widening demand overhang, a steadily declining mineral reserve base, compounded by limited exploration success and relatively high barriers to entry. The chances of any future mine discovery replicating the unique properties of the Argyle Diamonds Mine, is extremely low.
Currently there are no other pink diamond mines or deposits, and even if another deposit of pink diamond-bearing ore is discovered, it takes on average 10 years for a mine to proceed from discovery to production.
Inventories of diamonds are at historically low levels with significant stockpiles reduced to working capital levels over the past decade.
