Diamonds are forever. Some of this precious stones are more than billion years old. Diamonds may be a girl’s best friend, but they are also super-expensive gemstones. The most expensive diamonds are valued at several millions of dollars. The biggest buyers of expensive diamonds are men who buy them for their collections, (sorry ladies). These collectors are unsurprisingly amongst the world’s wealthiest men, they prize perfection and will pay in large amounts to acquire it.
