Strategically investing in rare natural fancy colored diamonds can offer solid returns. The best strategy is to obtain colored diamonds today at our competitive prices and hold onto them for the next four to six years, at least until Australia’s Argyle Mine stops production in 2018. When the world’s biggest supplier of natural fancy colored diamonds closes its doors, astute investors are expected to have a distinct advantage in a time of high demand and very little supply.
